Manual:wfTimestamp/bn
Overview
wfTimestamp() (part of GlobalFunctions.php) provides functionality to convert between common timestamp formats, including MediaWiki timestamps, UNIX timestamps, MySQL DATETIME format, RFC 2822 format and more.
See formats below for a full list.
Timestamps will be output without a timezone or in the GMT timezone, as specified by the particular format.
Never use wfTimestamp() when inserting a timestamp into the database. This will break in Postgres and possibly other non-MySQL databases. Instead use $dbw->timestamp()

wfTimestamp( $output_format, $timestamp )
- Returns a timestamp of type string in the format specified by the
$output_formatargument. - Throws
MWExceptionif an incorrect formats is passed via the$output_formatargument. - Returns
falseif an invalid or unrecognized timestamp is passed via the$timestampargument.
| Argument | Default | টীকা |
|---|---|---|
$output_format
|
TS_UNIX
|
Must be one of the constants listed in the formats table. |
$timestamp
|
এখন সময় | Should be a literal timestamp (e.g. 2010-12-03 22:07:25). Any format listed in the formats table can be used.

- Call with no arguments to return the current time in UNIX time format.
echo wfTimestamp(); // 1734718779
- Call with one argument to return the current time in the specified format.
echo wfTimestamp( TS_ISO_8601 ); // 2024-12-20T18:19:39Z
- Call with two arguments to return an arbitrary timestamp in the specified format.
Note that the timestamp can be in any format that wfTimestamp() can output.
$timestamp = 20241239181939;
echo wfTimestamp( TS_ISO_8601, $timestamp ); // 2024-12-20T18:19:39Z
$timestamp = '2024-12-20T18:19:39Z';
echo wfTimestamp( TS_RFC2822, $timestamp ); // Fri, 20 Dec 2024 18:19:39 GMT
