Calculating time (adding minutes) bash
Try this (Kysu's version):
date -d "16:00 410 minutes" +'%H:%M'or this:
date -d "16:00 today + 410 minutes" +'%H:%M'But do not use this:
date -d "16:00 + 410 minutes" +'%H:%M' # BAD!Strange things happen if you omit the word today but keep the +. (I think the + 410 is being parsed as a timezone modifier, and then the minutes is interpreted as "add one minute".)
