TimeZone.TryFindById

Looks up a time zone by IANA id, returning false when there is no such zone.

Syntax

TimeZone.TryFindById( byref zoneId as const ustring, byref result as TimeZone ) as boolean

Notes

• The id is checked before any file is touched: letters, digits, _, + and - in segments joined by /. Anything else, .. included, is simply not found.
• A link keeps the name asked for: US/Eastern is US/Eastern, with New York's rules.

Examples

#import "std/tz"
#import "std/tzdata"
#import "std/chrono"
using tz
dim as TimeZone z
print TimeZone.TryFindById( "Asia/Tokyo", z )       '' true
print z.Id                                          '' Asia/Tokyo
print TimeZone.TryFindById( "Mars/Olympus", z )     '' false
