WP_Posts_List_Table::column_date( WP_Post $post )

Compatibility

Present in every tracked release (6.7.7 to 7.1.0), and compiles on PHP 7.4 through 8.6-dev.

Parameters

$postWP_Post

The current WP_Post object.

Performance profile

How much work a call to WP_Posts_List_Table::column_date() 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

Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions

37–69

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 89.

Plugin surface

2 hooks

Third-party callbacks on 'post_date_column_status', 'post_date_column_time' run inside this call, and their cost is not bounded by anything here.

Called by

0

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

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

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 · 2 distinct outcomes

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

Hooks and filters fired · 2

2 hooks fire while WP_Posts_List_Table::column_date() runs, in this order:

1. 1
   apply_filters( post_date_column_status )filterline 1235 (+42 into the body)

2. 2
   apply_filters( post_date_column_time )filterline 1254 (+61 into the body)

Uses · 4

• __()Retrieves the translation of $text.
• get_the_time()Retrieves the time of the post.
• get_post_timestamp()Retrieves post published or modified time as a Unix timestamp.
• apply_filters()Calls the callback functions that have been added to a filter hook.
