Convert a meeting’s full date and time rather than relying on a remembered offset.
Use the Time Zone Converter alongside this illustrative example.
A practical example
For a meeting with colleagues in London and New York, enter the actual meeting date and the named source zone. Repeat for a date near a daylight-saving change: the two cities do not necessarily change clocks on the same day, so a familiar five-hour difference may not apply.
Check the result
Record the converted calendar date as well as the time, especially when a meeting crosses midnight. Use named city zones instead of ambiguous abbreviations such as CST.
Try a comparison
Make a second conversion for the following week using the same local meeting time. Around a clock change, another city’s time may shift even though the organiser’s wall-clock time stays fixed. Include the date in reminders to avoid a stale offset.
What this does not establish
Rules depend on the timezone data available to the browser. Recheck important appointments against the calendar invitation and keep the device software current.
