     181#: This extended :class:`doctest.OutputChecker` allows the following
     182#: additional matches when looking for output diffs:
     183#:
     184#: `N.NNN seconds`
     185#:    matches strings like ``12.123 seconds``
     186#:
     187#: `HTTPError:`
     188#:    matches ``httperror_seek_wrapper:``. This string is output by some
     189#:    virtual browsers you might use in functional browser tests to signal
     190#:    HTTP error state.
     191#:
     192#: `1034h`
     193#:    is ignored. This sequence of control chars is output by some
     194#:    (buggy) testrunners at beginning of output.
     195#:
     196#: `<10-DIGITS>`
     197#:    matches a sequence of 10 digits. Useful when checking accesscode
     198#:    numbers if you don't know the exact (random) code.
     199#:
     200#: `<YYYY-MM-DD HH:MM:SS>`
     201#:    matches any date and time like `2011-05-01 12:01:32`.
     202#:
     203#: `<DATE-AND-TIME>`
     204#:    same like ``<YYYY-MM-DD HH:MM:SS>`` but shorter.
