Override the default timezone #64

Open joelstein opened 4 months ago

Would you consider adding a feature to set the default timezone that Tempo would use to format dates?

Perhaps deviceTZ() could be enhanced to consult a default timezone override, falling back to the device timezone if unset?

isn't tzDate() enough though? I asked similar question for UTC in an issue that I closed not long after getting more info from the author in this comment

So yes, if you want to create the utc time, in utc you can do tzDate('2020-02-04', 'utc'), but you can also do tzDate('2020-02-04T09:30', 'America/New_York') which would return a Date object (utc timestamp) for 9:30am on Feb 4th, 2020 in new york.

see tzDate docs

Thank you. I'm primarily concerned with formatting the dates. All of my dates come from the server in UTC, but I always want them displayed in the website's local timezone (which may be different than the user's timezone).

That's why I think being able to set a default format (or display) timezone would be useful.

As it is now, I have to remember to set the timezone in every call to format() (and there are many in this application we're building).
