Those don't look to be 'unix time'[1] format ... particularly easy to
note/recognize, since we quite recently passed[2]
1234567890.

Conversions, ... I'd typically grab perl(1) ...
been there, done that[3] ...
or use some of the capabilities of GNU's date(1)[4],
... or perhaps in C if I was really going to be pounding
away at it.  There's also likely a Python answer
somewhere back on that earlier thread[5].
