Description

In continuation of #1329 and of gogs/gogs#4341 (of gogs project).

I think the updated time of mirrors in explore page should only be updated when someting changed in the mirror repo. This way, the firsts repos in the explore menu are only the most recently changed one.

They did it in this commit: gogs/gogs@8d04174

What's the policy on using code from gogs post-fork? If it's ok, I can create a PR with the linked code above.

I have >200 mirrored projects and so this ticket would be very useful for me.

There are some time for mirrored repositories.

1. Last Synced Time
2. Lastest Commit Time
3. Last Updated Time
   Maybe theses times should be treated different
