Manual:Timestamp/pl
The format of timestamps used in MediaWiki URLs and in some of the MediaWiki database fields is yyyymmddhhmmss.
For example, the timestamp for 2024-11-29 04:04:23 (UTC) is 20241129040423.
The timezone for these timestamps is UTC.
MediaWiki's wfTimestamp() function provides a convenient way to convert from timestamps in common formats to the MediaWiki timestamp format and vice versa.
Read Manual:wfTimestamp for more details.
Never use wfTimestamp() when inserting a timestamp into the database; this will break in PostgreSQL and possibly other non-MySQL databases.
Instead use DatabaseBase::timestamp(), aka $dbw->timestamp(), which converts a timestamp in one of the formats accepted by wfTimestamp() to the format used for inserting into timestamp fields in this DBMS.
wfTimestampNow() is a convenience function that returns a MediaWiki timestamp for the present time.
MediaWiki stores timestamps as strings rather than native timestamp types because MySQL's TIMESTAMP type had major limitations when MediaWiki was first written.[1]
