Frequently asked

Does it handle daylight saving correctly?

Yes. We use Intl.DateTimeFormat with IANA zones, which knows the correct DST rules for every supported zone.

Can I share my roster?

Not yet via a link. For now, copy the roster from your library or use the embed feature on the GenMB platform.
