internationalization - How is the Australia/Melbourne and Australia/Victoria treated in NodaTime? -

i have started using nodatime , noticed little problem.

based on wiki page https://en.wikipedia.org/wiki/list_of_tz_database_time_zones

australia/melbourne should have dst time shift +11 , non dst time shift +10. in nodatime looks austrralia/melbourne +10/+10.

on wiki australia/melbourne similar australia/victoria in nodatime australia/victoria +11/+11

where source of truth? wiki outdated or nodatime db not in sync? or maybe there other fascinating problem happening.

where source of truth?

the iana time zone database best source i'm aware of, , that's noda time uses.

if want see results of , have been on time, tzvalidate page has list of files, 1 per iana release. each file shows every transition in every time zone between 1900 , 2035.

now, i'm not seeing results are, suggests you're not using noda time correctly. here's example:

using nodatime; using system;  public class program {     public static void main(string[] args)     {         var zone = datetimezoneproviders.tzdb["australia/melbourne"];          var start = instant.fromutc(2015, 1, 1, 0, 0);         var end = instant.fromutc(2020, 1, 1, 0, 0);         foreach (var interval in zone.getzoneintervals(start, end))         {             console.writeline($"{interval.start} - {interval.end}: {interval.walloffset} {interval.name}");         }     } } 

output:

as can see, is +10 standard time , +11 daylight time.
