Date Formats

    Some commands allow the user to specify a date, e.g.:

    - backout, commit, import, tag: Specify the commit date.
    - log, revert, update: Select revision(s) by date.

    Many date formats are valid. Here are some examples:

    - "Wed Dec 6 13:18:29 2006" (local timezone assumed)
    - "Dec 6 13:18 -0600" (year assumed, time offset provided)
    - "Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000)
    - "Dec 6" (midnight)
    - "13:18" (today assumed)
    - "3:39" (3:39AM assumed)
    - "3:39pm" (15:39)
    - "2006-12-06 13:18:29" (ISO 8601 format)
    - "2006-12-6 13:18"
    - "2006-12-6"
    - "12-6"
    - "12/6"
    - "12/6/6" (Dec 6 2006)

    Lastly, there is Mercurial's internal format:

    - "1165432709 0" (Wed Dec 6 13:18:29 2006 UTC)

    This is the internal representation format for dates. The first number is
    the number of seconds since the epoch (1970-01-01 00:00 UTC). The second
    is the offset of the local timezone, in seconds west of UTC (negative if
    the timezone is east of UTC).

    The log command also accepts date ranges:

    - "<DATE" - at or before a given date/time
    - ">DATE" - on or after a given date/time
    - "DATE to DATE" - a date range, inclusive
    - "-DAYS" - within a given number of days of today
