If the GNUstep time zone datafiles become too out of date, one
|
|
can download an updated database from <a href ="ftp://elsie.nci.nih.gov/pub/">ftp://elsie.nci.nih.gov/pub/</a>
|
|
and compile it as specified in the README file in the
|
|
NSTimeZones directory.
|
|
|
|
Time zone names in NSDates should be GMT, MET etc. not
|
|
Europe/Berlin, America/Washington etc.
|
|
|
|
The problem with this is that various time zones may use the
|
|
same abbreviation (e.g. Australia/Brisbane and
|
|
America/New_York both use EST), and some time zones
|
|
may have different rules for daylight saving time even if the
|
|
abbreviation and offsets from UTC are the same.
|
|
|
|
The problems with depending on the OS for providing time zone
|
|
info are that some methods for the NSTimeZone classes might be
|
|
difficult to implement, and also that time zone names may vary
|
|
wildly between OSes (this could be a big problem when
|
|
archiving is used between different systems).
