How to subtract time by 10 minutes in datecalc tool
Hi guys.

I am trying to subtract 10 minutes from the current Unix system date and time. I have the datecalc provided here but it is mainly the date and not the time. Please check on how can i subtract 10 minutes from the current time using datecalc or any other shell scripting that will give almost similar format as follows:

Example:
Current Date Time:
2010-08-03-15.10.02

Afte subtracting 10 minutes should be:
2010-08-03-15.00.02

Thanks in advance.

If you have GNU date you can do:
Code:
$> date
Di 3. Aug 16:10:51 CEST 2010
$> date --date="10 minutes ago" "+%Y-%m-%d-%H.%M.%S"
2010-08-03-16.00.52

Else you might read up here for other solutions:

Thanks zaxxon for the swift response.

With regards to your response, unfortunately we do not have the GNU date here. I will try to check also the link you provided.

Regards,
Elly
