How to debug functions depending on (current-time)?

[Marcin Borkowski]

Hi all,

I have a bunch of functions depending on (current-time), and I'm
wondering how to test/debug them.  Is it safe to (temporarily) redefine
`current-time'?  Maybe it's better to do that in a separate Emacs
instance?  I could of course change their source code for the time of
debugging, but this still lefts the problem of testing (esp. automatic
testing) open.

Best,
