Even on Linux systems you may want to use perl

If the date binary doesn't exist but the perl one does

Thanks for the patch. Sorry for not replying earlier, I didn't get a notification from Github :-(

Just out of curiosity, on which Linux Distro was the date binary missing?

Struggling to remember, I think it may have been a docker container. They start off fairly barebones with very little.

I would nearly do it this way, ignoring platform:

if perl exists use perl way else if date exists use date way else error message stating you need date for perl

Or else just use perl everywhere, less dependencies to track, it's very rare that perl isn't installed, that's only the case is very embedded systems, android, RTOS's that kind of case I think? Which is rare
