UNIX Timestamp Converter

UNIX timestamps and time are converted to each other. UNIX timestamp (UNIX epoch, UNIX time, POSIX time or UNIX timestamp in English) is the number of seconds elapsed since January 1, 1970 (midnight of UTC / GMT), regardless of leap seconds.

UNIX timestamp converter tool supports the mutual conversion of time and UNIX timestamp. Time displays local time (current time zone time) and UTC time. UNIX timestamps support second and millisecond units.

1. Single Convert : Input a single Unix Timestamp and convert it to a time string. Input a single time string and convert it to Unix Timestamp.
   1. UNIX timestamp to time: fill in the timestamp to be converted in the timestamp input box. After filling in, select the timestamp unit. Click Convert to convert UNIX timestamp to time.
   2. Time to UNIX timestamp: fill in the time to be converted in the time input box. The supported time formats are 2022-01-10 19:21:59 and 2022-01-10 19:21:59.123, After filling in, click Convert to convert the time to UNIX timestamp.
2. Batch Convert : Input multiple times or timestamps to convert time formats. The input and output timestamps support seconds and milliseconds. The input and output time support custom time formatting strings and time zones. Batch conversion supports local time and all UTC time zones.
   1. When converting batch time to timestamp, if the Time Format contains time zone information (Z or ZZ), the time zone information in the time format will be used, ignoring the selected time zone information in the Time Zone.
3. Custom input format time format string.
