Thanks, I searched before I posted but didn’t see that discussion.
I think it would be clearer for users if it were shown without the Etc/ prefix, and GMT-7 were the same as America/Los_Angeles, but I guess that would cause surprises for people who are already doing something with the dates programmatically.
I think it’s quite easy to overlook that Los_Angeles and GMT-7 aren’t the same thing.
LA is in either PDT (GMT-7) or PST (GMT-8) depending on the time of year, and the clock changes occur in different countries at different times (UK: last Sunday in March and last Sunday in October, vs US second Sunday in March and first Sunday in November) so the offset will vary.
That’s why date/time systems usually show both the time zone and the offset.
Thanks, we’re aware of the clock changes, but people who do find GMT-7 (or GMT-8 at another time of the year) in the timezone picker might not realize that the dates they entered aren’t what they intended. Or when they see something like this, it won’t make sense, because LA is GMT-7 at the moment:
