YYYYMMDD HHMMSS [TZ] ?

[Karl Berry]

date -d can understand YYYYMMDD HHMM [TZ].
Would YYYYMMDD HHMMSS [TZ] be possible?

I'd love it if YYYYMMDD.HHMMSS and/or YYYYMMDD.HHMMSS.TZ could be
supported too (this is a very convenient format since it's a number that
can be sorted), but I think I already asked for that and it was
problematic for some reason.  So the form with the spaces is the next
choice ...

Thanks,
Karl
