So, the question boils down to what operating system are you running? (If Linux or you have access to the GNU date utility, you can use what Scrutinizer suggested. If not, do you have access to a recent version of the Korn shell (93u+ or later)? If so, you can use ksh's printf built-in's %(format)T format specifier to do the same thing. If not, do you have perl installed. ...) We need to know the environment you're using to tell you how to get what you want as easily as possible.

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
