  • 5.3.0

Retrieves the current time based on specified type.

- The 'mysql' type will return the time in the format for MySQL DATETIME field. - The 'timestamp' or 'U' types will return the current timestamp or a sum of timestamp and timezone offset, depending on $gmt. - Other strings will be interpreted as PHP date formats (e.g. 'Y-m-d'). If $gmt is a truthy value then both types will use GMT time, otherwise the output is adjusted with the GMT offset for the site.
