Great idea! Anyone on the list know if there's a way to make the debug log facilities do the YYYYMMDD timestamp instead of the longer one?
If not, I suppose we could work to update the core MediaWiki code. [1] -Adam 1. For those with PHP skills or equivalent, I'm referring to https://git.wikimedia.org/blob/mediawiki%2Fcore.git/a26687e81532def3faba64612ce79b701a13949e/includes%2FGlobalFunctions.php#L1042. Scroll to the bottom of the function definition to see the datetimestamp approach.
