But *why* do you want to set the system clock ahead 2.5 hours?  It's
such a bizarre request that you must be doing it to solve some other
problem, which can perhaps be solved more directly (e.g. by using Bob's
faketime approach, if the problem you're really trying to solve is
"run this program and make it think that it's 2004 to work around the
stupid license").

Another possible problem you might be working on is "tell me what time
it is in this other time zone", in which case you just want to invoke
date(1) with the TZ variable set appropriately, like so:

cyclops:~$ date; TZ=US/Pacific date
