Converts a dated local time to chosen IANA zones using the browser's time zone rules. No live time service; times that repeat or do not exist during a DST change show an error.

Examples

Across midnight

2024-03-10 21:30 America/Los_Angeles
Europe/Berlin: 2024-03-11 05:30
Asia/Kolkata: 2024-03-11 10:00

On that date Los Angeles is on daylight time (UTC-7), so Berlin and Kolkata show the next day. Times that occur twice or do not exist during a DST change produce an error; choose another time. Rules come from your browser, not a live time service.
