Your statement can be ambiguously parsed as "I need to merely
*generate* time specifications that 'at' can parse", or it can be
parsed as "I need to generate *and consume* time specifications the
same way as 'at' does"

If it's the former, it's pretty easy--'at' accepts a wide variety of
formats.

If it's the latter, I've got a doc in

  /usr/share/doc/at/timespec

on my Debian machine, which seems to be googleable, but here's one
copy of it

I don't have a parser already, but that should get you a jump start
on what (at least Debian's) 'at' parses, and might tie nicely with
pyparsing.
