Steps to reproduce were very easy.
Run a clean install of Jenkins 2.263.4
java -DJENKINS_HOME=2.263 -jar jenkins-2.236.4.war
Skip the wizard steps ( so skip plugins, initial user, etc.)
got to http://localhost:8080/pluginManager/available
(set up proxy in Advanced first 'cos behind firewall)
Check Now to obtain list of available plugins
Filter on "plugin" ('cos everything is returned)
Sort by Released , click for Up, then for Down, observe.
Observe that under 2.263.4, the list of plugins is sorted correctly chronologically
It's all as expected; hours, then days, months, years (see image).
Rinse and repeat for 2.277.4
java -DJENKINS_HOME=2.277 -jar jenkins-2.277.4.war
Observe that under 2.277.4, it is not:
1 mo, then 1 yr, 10 mo, 11, mo, then 2 mo, 2 yr, etc.

This is not a recent regression. I installed 2.277.4 (the oldest version of Jenkins still supported by the Update Center at the time of this writing) with the default list of suggested plugins and can reproduce the problem there. Because this is not a recent regression I am removing the regression label from this PR.
