Subtracting Time from strftime

2004-01-28T11:04:12-04:00

To write the current time - 10 minutes:

Code:

strftime %H:%M [expr {[clock seconds]-600}]

To subtract 10 minutes from an existing timestamp:

Code:

strftime %H:%M [expr {[clock scan $theStamp]-600}]

Subtracting Time from strftime

2004-01-28T09:40:35-04:00

Ok, right now in my script, to mark the current time, it uses [strftime %H:%M]. Now my question is, how would I go about taking that time, subtracting 10 minutes off it, then writing the time.

This is all part of my server status script for a webpage. But the webpage has a 10 minute delay. And I want to be able to write to file the RIGHT time the server came up, not 10 mins after it came up.

Help would be greatly appreciated.
