in localtime $_
optional: without it, the function returns current
local time; likewise gmtime()
The -l (that's a small ell) command line switch may be useful: it will automatically chomp the input record separator (IRS) on input and append the ORS on output. (IRS and ORS are both a newline by default.) As mentioned, not so important on input, but on output this gives you your converted time strings each on a separate line rather than as one (very long) line.
>perl -wMstrict -lne "print scalar localtime $_" < utimes > ltimes
>perl -wMstrict -lne "print scalar gmtime $_" < utimes > gmtimes
