| 32 | * This set of patterns is designed to parse a specific time of a specific day, |
| 33 | * since that's what the scheduler needs. Other requirements might need other |
| 34 | * pattern lists. |
| 35 | * |
| 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. |
