Hello! my current timezone is UTC+0200. I create a test repo, add one commit and create a tag: Now: $ git for-each-ref --format="%(taggerdate:format:%s)" refs/tags 1588504146 $ date +"%s" 1588500585 $ git for-each-ref --format="%(taggerdate:raw)" refs/tags 1588500546 +0200 Somehow %(taggerdate:format:%s) gives a Unix timestamp which is one hour in future and it is different than what ` date +"%s"` gives around approximately the same time the tag was created. clime
