Revision f4fd6276619dfe7cf9a024730ca65b1bd0b3492b authored by Junio C Hamano on 12 August 2016, 16:16:56 UTC, committed by Junio C Hamano on 12 August 2016, 16:16:56 UTC
Not-so-recent rewrite of "git am" that started making internal calls into the commit machinery had an unintended regression, in that no matter how many seconds it took to apply many patches, the resulting committer timestamp for the resulting commits were all the same. * jk/reset-ident-time-per-commit: am: reset cached ident date for each patch
