ironically i based the time off of similar aliases i made using irssi's
exec command and some simple one line shell commands. in fact, i made them
to convert from utc to local and vice versa as well as for any other time
zone:

> 2local     exec - date -d 'TZ="UTC" $0-'
> 2localbytz exec - date -d "$0-"
> 2utc       exec - TZ=UTC date -d "$0- `date +%Z`"
> 2utcbytz   exec - TZ=UTC date -d "$0-"

I don't use any specific format because date's [string format][1] is really
flexible. of course, your script guarantees success, but date strings
pretty much do, too (especially check out the relative items) :)

usage is simply /script <date string>. just make sure for the ones that end
in bytz to add a descriptor for the time zone, e.g. UTC-7 or PST, though i
don't recommend the latter as it's potentially ambiguous. one thing it
won't accept is zoneinfo format (e.g. America/Los_Angeles). that being
said, you'll have to be sensitive to your own daylight savings time/summer
time.

with that, the non-bytz ones are somewhat extraneous but it keeps me from
having to type anything extra or figure out DST, since it leverages date to
get the current local time zone.

so you can see, i had a very refined system for dealing with the issue of
date and time conversions. the problem was, i tried to figure out what time
I'd show up at work rather than what time I'd be available. lesson learned:
no one is safe from the malicious hand of PEBKAC.
