| 4 | # No attempt is made to handle Newfoundland, since it cannot be expressed | |
| 5 | # using the System V "TZ" scheme (half-hour offset), or anything outside | |
| 6 | # North America (no support for non-standard DST start/end dates), nor | |
| d1ccfde8 | 7 | # the changes in the DST rules in the US after 1976 (which occurred after |
| b51d5b5f | 8 | # the old rules were written). |

| d1ccfde8 | 10 | # If you need the old rules, uncomment ## lines. |
| b51d5b5f | 11 | # Compile this *without* leap second correction for true conformance. |
