Click is the only Star Wars unit of time I'm aware of. Although I have no idea what amount of time it represents in terms of the real world...
But apart from that they use the same time terms as we do e.g. 'hour'. In A New Hope Han Solo says:
"Anyway, we should be at Alderaan in about 0200 hours."
They also have minutes and seconds. And strangely, all of the main references to time are made by Han Solo...
EDIT: Wait, I found this on the Galactic Standard Calendar Wookiee page:
And the days of the week are:
In the galaxy:
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
5 days = 1 week
7 weeks = 1 month
35 days = 1 month
368 days = 1 year
10 months + 3 festival weeks + 3 holidays = 1 year
