The options are straight out of the tzdata database files. It has not been decided to make things more simpler and reduce redundant or confusing options. Tomato has not even bothered to update to current data. _________________ "The woods are lovely, dark and deep,

regarding the regulatory domain, that option has disappeared from DIR-868L Rev.A1 for a few years. Currently the workaround is to load the old ddwrt firmware, change the regulatory domain setting, then upgrade to the newest firmware, I'm not sure if there's any command to change the nvram directly. But this is not related to the topic so we can discuss in details elsewhere.
The special area of "Etc" is used for some administrative zones, particularly for "Etc/UTC" which represents Coordinated Universal Time. In order to conform with the POSIX style, those zone names beginning with "Etc/GMT" have their sign reversed from the standard ISO 8601 convention. In the "Etc" area, zones west of GMT have a positive sign and those east have a negative sign in their name (e.g "Etc/GMT-14" is 14 hours ahead of GMT).
By the way, all the zones are listed under the following link.
there you can also see that singapore is a link to asia/singapore
Quote:
Canonical - The primary, preferred zone name.
Link - An alternative name (alias) which links to a canonical zone.
Link†
- A standard Link (as above). The dagger symbol (†) signifies that the zone was canonical in a previous version of the database. Historical data for such zones is still preserved in the source code, but it is not included when compiling the database with standard options.
and for Hong Kong is "Asia/Hong_Kong" the current and correct time zone name and nothing else
It is true that the countries in the GMT+8 zone all have the same time, but this was not always the case.
For example, DST (Daylight saving time) plays a role.
And the question of the thread creator was what is the correct time zone for Singapore and not what is a wrong time zone that leads to the same result.
