If you're one of those "give me a terminal or give me death" master race kind of person, then I have a little shell script I use for this:

  % tz
  US West        18:39 -0800 PST
  US East        21:39 -0500 EST
  UTC            02:39 +0000 UTC
  Ireland/UK     02:39 +0000 GMT
  West Europe    03:39 +0100 CET
  New Zealand    15:39 +1300 NZDT
  
  Current        02:39 +0000 GMT
  
  % tz 18:00
  US West        10:00 -0800 PST
  US East        13:00 -0500 EST
  UTC            18:00 +0000 UTC
  Ireland/UK     18:00 +0000 GMT
  West Europe    19:00 +0100 CET
  New Zealand    07:00 +1300 NZDT
  
  Current        18:00 +0000 GMT

I find it's pretty convenient anyway.

I use something similar, but I use -d "$*" instead of -d "$1" so I can do

    $ dates 4 hours ago

One of two times "$*" had been useful

[arp242]

I didn't know date supported that – can still do that with "tz '4 hours ago'".

For me the most useful part is being able to quickly translate things like "let's do a video chat at 3pm PST" to something that makes sense, which is why it had the second argument to set the timezone.
