Timezone Converter – Quick Cheat Sheet

Input time is interpreted in the selected From time zone (not the server time zone).
Offsets (e.g., UTC+05:30) can change by date due to Daylight Saving Time. Always convert for the exact date.
Conversions preserve the same moment in time; only the wall-clock representation changes.
24-hour vs 12-hour: both are shown for clarity, with current zone abbreviations (e.g., CST, CDT, JST).
Difference shows how far ahead/behind the destination is relative to the source at that moment.
Tip: Some zones have 30- or 45-minute offsets; verify unusual results by checking the zone abbreviation and offset.

Edge cases & notes

Ambiguous or skipped local times can occur around DST transitions. If a local time doesn’t exist or is ambiguous, adjust by a few minutes.
Zone lists come from PHP’s DateTimeZone::listIdentifiers(). If a specific zone isn’t available on your system, update PHP/ICU.
