Modern Tz TimeZone Local

TimeZone.Local

Returns the machine's own time zone, answered by the operating system.

Syntax

TimeZone.Local( ) as TimeZone

Notes

• It agrees with TimeZoneInfo everywhere.
• Its Id is the machine's IANA id where one can be found: from TZ or /etc/localtime on Linux and macOS, and on Windows from the zone's Windows name through CLDR's table when the zone can be loaded. Otherwise it is "".
• Transitions of the Local zone are found by scanning ten years a day at a time: a change further away is not reported.

Examples

#import "std/tz"
#import "std/tzdata"
#import "std/chrono"
using tz
dim as TimeZone here = TimeZone.Local( )
print here.IsValid          '' true
