Re: [PATCH] pretty format string support for reflog times

I am not sure about the latter, i.e. the return value from the
get_reflog_time_t() function (which I think is misnamed, in that the
function returns "unsigned long", not "time_t", and should be
renamed to get_reflog_time()) uses the epoch as a fallback value.
