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.

To subtract 10 minutes from an existing timestamp:
