Multiple clocks and time zones in LXDE

[mohack]

Hi!
I need multiple clocks (three at least) on my desktop, preferably directly on the panel. I already found out how to add a second clock as a panel item in LXDE, but I can't find a way to set it to a different time zone. For example, in Win7 I can set up three different time zones, so that when I hover over the task bar clock all three times are shown.
Is there a way to use a similar feature in LXDE?
Thanks!

Put "clock" in synaptic search to bring up many clocks that can be installed. Don't know if any will show multiple times with one launch, however.

Thanks. I was looking for a LXDE taskbar solution, but there doesn't seem to be one. I now use gworldclock, it's not pretty but it does what it's supposed to.
