Newer versions of git would respect it, and older > versions would fall back to using the committer timestamp. Suggestion add a ms offset field. Ex: jpyeron@black /projects/git/git $ git cat-file -p HEAD tree 1e24acfbfcc05aa57e8cb2cfe3ffe01cb100961d parent e98fa647aa5673cc95b6e9be1fdc13c0afa2cb37 author Junio C Hamano <gitster@xxxxxxxxx> 1350495361 -0700 committer Junio C Hamano <gitster@xxxxxxxxx> 1350495402 -0700 mstimestamps author 0 committer 1234 Git 1.7.12.4 Signed-off-by: Junio C Hamano <gitster@xxxxxxxxx> > > But I really wonder if anybody actually cares about adding > sub-second timestamp support, or if it is merely "because SVN has it". Not because subversion has it but because date != git(precisedate) and some automation using git in a larger enterprise workflow may assume that date 1354065991.1234 going in should be the same when queried. -Jason -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
