$for_postint|booloptional

Accepts 1|true for applying the date to a post, 0|false for a comment.Default: 1

$tab_indexintoptional

The tabindex attribute to add. Default 0.Default: 0

$multiint|booloptional

Whether the additional fields and buttons should be added.
Default 0|false.Default: 0

Performance profile

How much work a call to touch_time() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Cost class

Heavy

Reaches the database via get_post().

Scaling

Scales with input

The body loops, so the work grows with what you pass in.

Instructions

159–208

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 317.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

2

2 places in core call this, so the cost is paid more often than your own code shows.

What it touches

• querycontent queryget_post()called directly
• hookthird-party callbacksapply_filters()one call below touch_time()
• optionoption read or writeget_option()one call below touch_time()

Further down the call graph this can also reach cache, serialize and transient. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.

What one call costs · 72 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost touch_time() can have, taken from its control-flow graph on PHP 8.5.

This body has more branch combinations than are worth enumerating, so the table covers the outcomes found first rather than every one that exists.
