UTC Time on Google App engine?

What's the best way to work out the time when my servlet in google app engine is hit ?

if I call System.currentTimeMillis() and store that info will it be reliable ?

I don't need milliseconds precision.

I just want to store an entity with the date on when it arrives.

Thanks

No, it won't be reliable.

In Dan Sanderson's book, "Programming Google App Engine" he says:

It's worth noting that App Engine makes no guarantees that the system clocks of all of its web servers are synchronized. <...> The server clock is not consistent enough as a source of time data for a real-world application, but it's good enough for this example.
