Translate between Epoch time (seconds since 1970) and standard calendar dates. Supports UTC and local time zones.
A Unix timestamp represents time as a count relative to the Unix epoch, commonly 1970-01-01 00:00:00 UTC.
Enter a timestamp and choose the correct unit, then convert it to a human-readable date and time.
Many systems use seconds for Unix timestamps, while some APIs and JavaScript environments commonly use milliseconds.
Unix timestamps represent an absolute point in time; display in a local time zone can make the same timestamp look different.
Historical and negative timestamps can be supported, but implementation ranges vary by language and platform.
Off-by-hours errors usually come from time-zone display, while thousand-fold errors commonly come from confusing seconds and milliseconds.
