Description

wfDebugLog() messages in the $wgDebugLog file are lacking time indications. It has neither date-timestamps (like the mediawiki error log file would), nor +0.01ms offset information (like profiling would).

This applies to the wgDebugToolbar feature as well.

I checked just now on a plain install of MediaWiki using mediawiki-docker-dev and with DevelopmentSettings.php loaded from LocalSettings.php.

I find that the error logs contain timestamps. Note that the $wgDebugTimestamps configuration variable is no longer supported as of MW 1.35. Timestamps are now enabled by default.

Checking the debug logs, I do not see timestamps there currently.

Checking the debug toolbar, indeed also no absolute or relative timestamps either:
