The following representation standards of dates and times are currently supported and can be use by setting check/date to:

• POSIX

  see STRPTIME(3) for more information. A valid format has to be specified in check/date/format

• ISO8601

  see ISO8601. Possible format strings specified in check/date/format, default: datetime complete+truncated:

  • Dates/Time:
    • Date:
      • calendardate calendar dates: day of month - month - year.
      • weekdate calendar week and day numbers, e.g. YYYY-Www-D
      • ordinaldate year + day of the year
      • date calendardate, weekdate, and ordinaldate combined
    • Time:
      • timeofday 24-hour timekeeyping system
      • utc coordinates universal time. either by appending a time-zone designator or the time difference to UTC to timeofday
    • Combined: datetime combination of Dates and Time according to th ISO8601 specification.
  • Representation: if no representation is specified, complete+reduced+truncated is used as default.
    • complete complete representation, dates are separated by hyphens, times by colon, e.g. YYYY-MM-DD or hh:mm:ss
    • reduced reduced precision, e.g. YYYY-MM, or hh
    • truncated truncated representation, hyphens used to indicate omitted components, e.g. –MM-DD or –ss
    • complete+reduced+truncated allow all 3 representations
    • complete+reduced allow only complete + reduced representation
    • complete+truncated allow only complete + truncated representation
    • reduced+truncated allow only reduced + truncated representation.
  • Format: if no format is specified both basic and extended are treated as valid.
    • basic no separating character between individual components of a date, time or datetime expression.
    • extended separating characters between components. date components separated by hyphen, time components by colon.

• RFC2822

  a set of possible format strings derived from rfc2822 3.3, no format string needed.

POSIX.1-2001

TBD

Testing timezone designators currently only works with glibc. Unit tests using timezone designators are locale dependent.
