moment-timezone include all data for specific timezone

[fran-worley]

Based on the options for including timezone data there doesn't appear to be a way to include all data for just one timezone. We only operate in the UK but hold data going back 20+ years so are currently having to import 'all'. It would reduce our build size if we could limit the import to just "Europe/London|Europe/Belfast".

Is there a way to do this?

There isn't an automatic way of doing this.

However, you can strip out the timezone data you need and manually register the data. Afterwards, be sure to set includeTimezone: "none".

Hopefully that help!

Thanks Jason,

I actually tried this originally but ran into issues where moment.tz was undefined so fell back to importing all. It's possible that I was attempting to manually register in the wrong place but either way I figured some docs might be useful for everyone given that build size is quite a hot topic with ember at the moment...

We're also looking for ways to reduce our build size, and moment-timezone is currently almost double the size of Ember itself in our bundle! Would love some suggestions on how to include less timezones and less locales for moment itself, etc.

@rwwagner90 Does this not cover your use case: https://github.com/jasonmit/ember-cli-moment-shim#cherry-pick-locales-optimal

@jasonmit that looks like it should work for locales. We currently have includeTimezone: 'all' as well though, so I assume we have to manually load timezone data? We don't actually want all timezones, I don't think, but I am not 100% sure which ones we do want now.

same here. a way to reduce the size due to timezone would be helpful
