Very odd time limit (e. g. “0.011574074074074 days”) on Special:RecentChanges

LucasWerkmeisterWMDE

On the Wikibase Registry wiki (wikibase-registry.wmflabs.org; MediaWiki 1.30.0), Special:RecentChanges shows a very odd time limit:

Show last 50 | 100 | 250 | 500 changes in last 0.011574074074074 | 1 | 3 | 7 | 14 | 30 days

Similarly on my watchlist:

Below are the last 0 changes in the last 0 hours, as of 9 May 2018, 12:02.
Period of time to display: 0.27777777777778 hours

Attempting to select any different timespan has no effect, making it difficult to review changes or fight vandalism on the wiki.

Has anyone seen this issue before, or do you have an idea what might cause this? @addshore and I are baffled.

It turns out that $wgRCMaxAge was set to a very low value (1000 seconds) in LocalSettings.php.
