Giro stage start time help

[dbrown]

I am going to be in Florence Italy on May 22, the day the Giro stage ends in Florence. I need to take the train to Pisa late in the day on the 22nd. I'd like to watch part part of the stage before going to Pisa, especially the end of the stage in Florence, if possible. I can't find what time the stage starts listed anywhere. Any ideas on where to look, or suggestions when the 150 km stage might end?

Thanks for any help you can give.
