Junio?\n\nNo it didn't.\n\nActually I didn't even think of that as a bug, in the sense that git never\naccepted fractional seconds and feeding such to git was a user error from\nday one; iow, 9f2b6d2 (date/time: do not get confused by fractional\nseconds, 2008-08-16) was an idiotproofing ;-)\n\nBut I'd agree perhaps we should cherry pick that one.\n"}]}
