So, Contador moves back into the pink jersey straight away. And he now has a large 2:28 gap on Fabio Aru at the top of the standings, with Andrey Amador up to third place at 3:36. Uran and Van den Broeck leapfrog Astana pair Caltaldo and Landa into the top five.

Confirmation of the stage victory for Team Sky's Vasil Kiryienka, who completed the 59.4km individual time trial in a time of 1:17.52. Luis Leon Sanchez (Astana) is second at 12 seconds and Alberto Contador (Tinkoff-Saxo) third at 14 seconds. Patrick Gretsch (Ag2R-La Mondiale) is fourth at 23 seconds and Steven Kruijswijk (LottoNL-Jumbo) fifth at 1:09.
Here comes Fabio Aru - and it's 29th place 3:01 down on stage winner Vasil Kiryienka of Sky.
Aru still one kilometre to go... earlier Andrey Amador set the 14th best time - and he may well be in third place on GC tonight.
Landa trickles over the line after his trubled effort, and we have just Fabio Aru on the road now. He won't finish for another five minutes or so because of the losses conceded to Contador.
Contador passes Landa before the finish, and he's close to taking the stage win... but he just misses out. Team Sky's Vasil Kiryienka holds on for the win, with Contador coming home 14 seconds down and just behind compatriot Luis Leon Sanchez of Astana.
Kreuziger comes home 3:52 down.
Dario Cataldo of Astana comes home in 36th position, 3:34 down on Kiryienka.
Contador is out of the saddle as he dances through the throngs of spectators towards the top of the climb ahead of the descent down to the finish. He'll be back in pink tonight and he'll have quite a gap.
At the third check at Col San Martino, Aru was 2:59 down on the leader - which is 2:08 down on his rival Contador...
Rigoberto Uran crosses the finish line after a torrid time trial - the Colombian comes home a huge 2:45 down on Kiryienka in 22 position. A shadow of the man who won last year's long time trial in Barolo.
It's the 30th best time at the finish, 3:17 down on Kiryienka, for Italy's Damiano Caruso (BMC).
Contador is grimacing his way towards the Col San Martino check point. He's fourth and so smashing his other GC contenders - but it probably won't be enough to topple Kiryienka for this stage.
15km remain for Fabio Aru, the last man on the road. He's improved in this hillier section of the course, but he will still lose his pink jersey this afternoon.
The fans are out in their droves on the Col San Martino, which Uran is currently tackling. Not the best time for Uran, but he's going to be better than Porte that's for sure.
Aru has been improving on the climbs and his deficit is down to 1:55 on Contador.
Belgium's Jurgen van den Broeck crosses the finish line 1:25 on Kiryienka in sixth place. Not bad for the Lotto Soudal rider, who will look to cement his position in the top ten today.
And here comes Aru... and the pink jersey is riding dangerously close to the local fans as he nears the top of this climb for the second time check... and it's a pained effort... way down in 45th place, three minutes down on Kiryienka - so already over two minutes down on Contador, who could have a 3min+ cushion at the finish.
Contador has set the eighth best time at the second check, 1:15 down on Kiryienka's target. But he's eating a huge amount from his rivals, with Aru said to be over three minutes down already...
Team Sky's Leopold Konig recovered to set the 10th best time at the finish, at 1:44.
Kreuziger may have caught Cataldo, but he's still 3:59 down at the second check - in lowly 76th position.
Uran is 3:10 down at the second check at San Pietro di Feletto. The Colombian is really struggling out there just like Porte...
Richie Porte is out of the saddle as he powers to the line - but he's 4:20 down in 41st place for the Australian. Even his Sky team-mate Elia Viviani was faster today...
It looks like Kreuziger will catch Cataldo on this climb to the second check.
Quick energy gel for Fabio Aru as he approaches the 25km mark.
Aru is 1:54 down at the first check, so that's 48 seconds down already. Contador back in the virtual pink jersey.
Mikel Landa - who has been a revelation so far - is over three minutes down at the first check, which is even worse than Porte. And here comes Contador, and he's just over a minute down for the 19th best time - which is pretty good considering the times we're getting through with these adverse conditions slowing the top riders considerably. 1:06 for Contador.
Live splits show that Contador is 11 seconds ahead of Aru and 34 ahead of Uran. The Spaniard has yet to go through the first check, though.
Luis Leon Sanchez has set the second best time at the finish: the Spaniard was third at the third check, but leapfrogged Gretsch towards the end. Sanchez is 12 seconds down on leader Kiryienka, who looks odds-on to win this one now the wind has apparently changed.
There's talk of the earlier tailwind having died away... which would make things very intriguing out there. The GC favourites may well finish well down on the likes of Kiryienka and Gretsch, but they will be having their own private battle for the pink.
Yes, it's true: Uran is 2:10 at the first split, which is slower than Porte. It will be interesting to see if that trend continues with the top five riders...
Well, if Porte's going badly then the same can be said for Uran: the Colombian is apparently 13 seconds down on Porte in the live splits. Perhaps the weather conditions have drastically changed?
Richie Porte's time at the second split at San Pietro di Feletto is not even in the top 25 best efforts out there today. Yep, he's 3:23 down on Kiryienka after the first climb.
Sardinian Fabio Aru (Astana) is ready to roll down the ramp. He's in a pink skinsuit but, mercifully, a blue helmet and white shoes/socks. His gloves are pink, mind. But all in all, he looks very elegant. One problem: he's never ridden a time trial as long as this in his entire career. Aru's on top now, but for how much longer?
Talking of Porte, he's on the uphill section now so we will get his second split time in a bit. Meanwhile, it's Alberto Contador who's now on course. He's struggled with his time trial position but he should still take time off Aru today - provided he doesn't come off his bike again. It remains to be seen how his sore shoulder copes with his position. It's said he's had to raise his bars a few millimetres - which could affect his aerodynamic position.
No one has troubled Kiryienka or Gretsch at any of the check points so far, the Belorussian and the German topping the standings in that order each time. Sky were hoping for the victory for Porte today - but they may well have one for Kiryienka instead.
Dario Cataldo is on course, and next up is Roman Kreuziger, the silent Czech assasin.
The rain is showing no sign of easing off - it's thoroughly miserable out there today, making those technical corners near the end very, very tough.
Just the Astana-Tinkoff-Saxo flavoured top five left to roll down the ramp. It's show time.
Porte is not the only Sky rider on the course - there's also Leopold Konig, who is two placed higher than the Australian on GC and riding equally badly. Meanwhile, down the ramp goes Rigoberto Uran - who is probably the big favourite for today's win, although he has been ill and has crashed a fair bit in this race so far, including once quite heavily on the Imola race circuit a few days ago.
Rigoberto Uran is preparing himself for his time trial. He won last year's 42km effort in Barolo - another wine region in northern Italy - and today he's even had a haircut in preparation, to get rid of those trailing Mick Jagger-style locks.
French national champion Sylvain Chavanel comes home 1:41 down on Kiryienka - that's level with Kristof Vandewalle.
Richie Porte is approaching the first check at Ponte della Pruila after 17.6km - and he's havimng a bit of a shocker. The Australian is well down on his team-mate Kiryienka's target time of 21:14. In fact, he's 1:57 down - that's three second shy of two minutes.
The last three riders to roll down the ramp were Damiano Cunego (Nippo-Vini Fantini), Jurgen van den Broeck (Lotto Soudal) and Giovanni Visconti (Movistar). We're into the top ten now...
One interesting snippet of information: Kristof Vandewalle (Trek) crashed into a wall on one of the fast and slippery downhills, but the Belgian still recovered to set the fourth best time at the finish - 1:41 down on Kiryienka's target time.
Italian youngster Davide Formolo rolls down the ramp in the white skin suit of best young rider (the stage 4 winner is actually the second best young rider on GC, but Fabio Aru's in pink today). The Cannondale-Garmin rider has been a revelation so far in this race.
The course takes the riders through Prosecco region today - but the question is, who will have the most vintage performance today? Incidentally, thanks to the UK's unquenchable thirst for fizzy Italian white wine, there could well be a prosecco drought this summer. Last year's wet summer coupled with aggressive pricing from larger supermarket chains have put big pressure on supplies, apparently...
Can Richie Porte turn his horror week around? The Australian national champion is on the ramp about to get his 60km race against the clock under way... Here he goes - one last chance to save his Giro d'Italia for the Team Sky man.
But Gretsch's time in the hot seat didn't last long: Vasil Kiryienka has just come home 23 seconds quicket than the German to set a new target time of 1:17.52.
Here comes Gretsch - and it's the best time by a huge 1min 13secs for the German from Ag2R-La Mondiale. It just goes to show how big the gaps could be for the top 10 today. Riders like Uran are still very much in this race, while Richie Porte could well revive his race with a decent ITT. So Patrick Gretsch is the new leader with a time of 1:18.15.
If/when Durbridge's time is beaten, it could well be by Team Sky's Vasil Kiryienka, who is currently beasting the course. The Belorussian has set the fastest time at both the first and second check points. Atop the first climb at San Pietro di Feletto after 35km, Kiryienka clocked 45:23 which was eight seconds quicker than Patrick Gretsch's effort for Ag2R-La Mondiale.
New best time for Australia's Luke Durbridge (Orica-GreenEdge) who takes almost of minute off the previous best effort. His time of 1:19.38 is 54 seconds quicker than Mihaylov and will probably be the target time for quite a while.
The top 20 riders on GC will be riding at three-minute intervals from 13:45 UK time, starting with Darwin Atapuma (BMC). Richie Porte (Team Sky) - one of the favourites today - will start at 13:54 UK time, Rigoberto Uran at 14:27, Alberto Contador at 14:39 and Fabio Aru at 14:42.
More than half the field have already rolled down the ramp, with the current best time being held by Bulgaria's Nikolay Mihaylov (CCC Sprandi Polkowice) at 1:20.32. Russian Alexander Porsev (Katusha) is in second place at 7secs and Denmark's Chris Juul-Jensen (Tinkoff-Saxo) in third at 14secs.
Starting in reverse order, the first rider down the ramp today was Marco Coledan of Trek Factory Racing at 12pm local time. It's another rainy day in north-east Italy which will make this technical course all the more testing.
Aru is all but certain to lose the pink jersey today - time trialling is not his forte at all - so it might well be a return to the summit for Contador. Indeed, we could even see the resurgence of Rigoberto Uran, who won last year's longer time trial. In fact, the Colombian - currently 2:02 down in the standings - put 2:55 into Aru over a 42.2km course last year... read into that what you will.
A reminder that Italy's Fabio Aru (Astana) became the first Sardinian to wear the maglia rosa yesterday after a crash 3.2km from the finish caused Alberto Contador (Tinkoff-Saxo) to lose 36 seconds yesterday. The Spaniard drops to second on GC at 19 seconds - marking the first time in his illustrious career that he has lost the race lead during a Grand Tour. Mikel Landa of Astana is third at 1:14, followed by Roman Kreuziger (TS) at 1:38, Dario Cataldo (Astana) at 1:49 and Rigoberto Uran (Etixx) at 2:02.
With nothing but mountains in the last week until the final stage to Milan, many sprinters have called it a day today ahead of the ITT. Australia's Michael Matthews (Orica-GreenEdge), Belgium's Tom Boonen (Etixx-QuickStep), Germany's Andre Greipel (Lotto Soudal) and New Zealand's Greg Henderson (Lotto Soudal) have packed their bags - and we can expect many more to do so at the close of play today.
The first half of today's course is flat before the road rises around 240m to San Pietro di Feletto. There follows a small downhill and a plateau ahead of a final climb back up to 323m at San Pietro Barboza and a quick downhill towards the finish, which comes atop a small ramp.
