Use ISO 8601 date format, with time zone appended if
change-log-time-zone-rule is non-nil, instead of traditional Unix date format. (datearg): When computing default from ChangeLog, handle ISO format dates in addition to old-fashioned dates from Emacs 19.31 and earlier. Don't worry about hh:mm:ss since the resolution is now by day. Use emtpy datearg, not empty rlog_options, to decide whether to pass "$datearg" option to $rlog. (logTZ): New variable, set to TZ specified by change-log-time-zone-rule. (month_data): Remove `mo'; no longer needed. (rlog_options): Use -zLT for localltime output, if `rlog' supports it. (extractTZ): Use UTC if the zone is t. Match `revision' line of rlog output more accurately. Add -c, -v options.
