I recently learned otherwise. Recent versions of mawk have borrowed this useful feature, possibly because some Linux distributions have taken to mawk as a faster substitute for GNU awk.

mawk-20121129 is the latest version. You can download the sources and easily build it on CentOS 6.

From the mawk changelog:
Code:
20121129
...
        + add systime and mktime functions
...
        + integrate strtime function (patch by Dominic Letz).

woot!

Code:
# mawk -W version
mawk 1.3.4 20131226
Copyright 2013, Thomas E. Dickey
Copyright 1996, Michael D. Brennan

internal regex
compiled limits:
max NF             32767
sprintf buffer      2040
# echo "hi" | mawk '{print systime()}'
1389377609
# echo "hi" | mawk '{print strftime("%D",1389377609)}'

Many thanks to everyone. I was certain that I had the latest version, but I must have misread.
