30/** @brief Date parsing patterns
31 *
32 * This set of patterns is designed to parse a specific time of a specific day,

34 * pattern lists.

36 * NB DisOrder now uses my_strptime() instead of the system strptime(). This
37 * has some bits missing. Therefore check carefuly before adding to this
38 * table.
