||| awk -F: -v days=60 \
|| 'BEGIN { from=systime(); to=from+(days*86400)};\

Todd Millert of sudo/OpenBSD mentioned that nawk (Kernighan's one
true awk) got systime(), but it is on the [bsd-features] branch of
the github repo[1] only, taken over among other things by Aharon
Robbins of gawk (i had opened an issue; 'and switched my CRUX
Linux port to that branch).
