| 8 | # that cannot use POSIX TZ settings. | |

28 | # We use POSIX-style signs in the Zone names and the output abbreviations, |
| 29 | # even though this is the opposite of what many people expect. | |
| 30 | # POSIX has positive signs west of Greenwich, but many people expect | |
| 31 | # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses | |
| 32 | # the abbreviation "GMT+4" and corresponds to 4 hours behind UTC | |
| 33 | # (i.e. west of Greenwich) even though many people would expect it to | |
| 34 | # mean 4 hours ahead of UTC (i.e. east of Greenwich). | |
| 35 | # | |
| 36 | # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation | |
| 37 | # (which is not yet supported by the tz code) allows for | |
| 38 | # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to | |
| 39 | # ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected | |
| 40 | # offset is kept within the angle bracket (and is used for display) | |
| 41 | # while the POSIX sign is kept outside the angle bracket (and is used | |
| 42 | # for calculation). | |
| 43 | # | |
| 44 | # Do not use a TZ setting like TZ='GMT+4', which is four hours behind | |
| 45 | # GMT but uses the completely misleading abbreviation "GMT". | |

| 50 | # We did not want things to change quietly if someone accustomed to the old | |
| 51 | # way does a | |
