Hi Monks,

I'm trying to check if the difference between 2 times is greater than 4 hours. I'm using korn shell, but am trying to use a perl one-liner within the shell script to return the value.

One issue is that one of the times i'm using in the calculation is HH only that is stored in a file. The other time is current HH from unix. So for example, if the HH from the file is 00 and the current HH from unix is 20 the diff is 20, but in reality the time diff is only 4.

Normally, I would include an attempted code snippet, but i just can't come up with anything.

any help is greatly appreciated..thanks
