you can likely convert your time values to seconds using the 'date' command, or do the math yourself
if the results of your expressions are all integers, your 'expr' commands will be ok.
otherwise, you can do all kinds of math using the 'dc' command
the 'dc' command takes a somewhat arcane arg list for setting precision, printing results, etc. It also uses postfix ops which pop entries off the stack. check out the man page, or the wikipedia page.
