Donovan, check the tcl manual for the command 'clock format'..
Here's an example..
[clock format [clock scan $Time] -format "%m/%d/%y %R"]
would result in a display of 04/09/10 17:53
Or.. [clock format [clock scan $Time] -format "%m/%d/%Y %I:%M"]
would result in a display of 04/9/2010 05:53
I use this one in my signature..
[clock format [clock scan $Time] -format "%h. %d @%l:%M %p"]
which results in "Apr. 9 @ 5:53 PM"
