How it works
One instant, many local times
Define the source
An explicit Z or UTC offset is respected. Otherwise, the selected source zone supplies the missing context.
Choose the destination
Moment Timezone applies the correct offset and daylight-saving rules for the selected date.
What does the Z at the end of a timestamp mean?
Z means the value is in UTC, also called Zulu time. For example, 08:00Z becomes 16:00 in UTC+8.
Does UTC+8 use daylight saving time?
China Standard Time, Hong Kong Time, and Singapore Standard Time remain at UTC+8 throughout the year.
Are my dates uploaded?
