All time zone data in Moment Timezone comes from the IANA Time Zone Database ("tzdb"). Moment Timezone consumes the default data directly from the tzdb, using only the published releases. The only changes the library makes are to convert the data to a custom JSON format, and optionally restrict how many years of data to use.
Any pull requests that make changes to the compiled data files without being derived from a tzdb release will be rejected.
If you think that the data used by Moment Timezone is incorrect, the ideal order of actions to follow is:
- Make sure you've upgraded to the latest version of the library. We try to closely track the tzdb releases, so upgrading Moment Timezone resolves most cases of out-of-date data.
- For data calculation problems, raise an issue in the Moment Timezone issue tracker.
- For other problems (such as creating a new zone definition), search the archives of the tzdb mailing list. It's probable that new data changes or zone definitions are already being discussed, but haven't made it to a published release yet.
- If there is nothing in the tzdb archives, send a message to the mailing list at tz@iana.org.
