What does Time Zone Converter actually do?

The timezone converter takes a civil time in one IANA zone and shows the same instant in another, including DST when the zone data says so. It does not schedule cron jobs. Abbreviations like EST are ambiguous; prefer names such as America/New_York.

When should I use Time Zone Converter?

Use it when a meeting time or log timestamp must be shown in another zone.

When should I not use Time Zone Converter?

Do not add offsets by hand and also convert here — pick one.

What does Time Zone Converter not do?

Three-letter abbreviations are not reliable zone ids. Does not parse cron.
