Question : How do I get the time only from a SQL datetime value?

I've googled this until my brain hurts and every example I try doesn't return the right thing.  I have this, in a datetime field:

'2007-03-17 13:25:00'

I need to query on the time only. (13:25:00)  How do I do this reliably?

Thanks!
