使用Nodatime将UTC时间转换为当地时间

我已经提供了这种格式“ddMMyyHHmmss”的时间。 我知道时间是UTC格式。 我想使用NodaTime库将其转换为我当地的时区，但我似乎无法弄明白。 我当地的时区目标是新西兰。

这是我尝试过的：

var pattern = LocalDateTimePattern.CreateWithInvariantCulture("ddMMyyHHmmss"); var parseResult = pattern.Parse(utcDateTime); if (!parseResult.Success) { throw new InvalidDataException("Invalid time specified " + date + time); } var timeZone = DateTimeZoneProviders.Bcl["New Zealand Standard Time"]; var zone = new ZonedDateTime( localDateTime, timeZone, timeZone.GetUtcOffset(SystemClock.Instance.Now)); return new DateTime(zone.ToInstant().Ticks);

 // Since your input value is in UTC, parse it directly as an Instant. var pattern = InstantPattern.CreateWithInvariantCulture("ddMMyyHHmmss"); var parseResult = pattern.Parse("150713192900"); if (!parseResult.Success) throw new InvalidDataException("...whatever..."); var instant = parseResult.Value; Debug.WriteLine(instant); // 2013-07-15T19:29:00Z // You will always be better off with the tzdb, but either of these will work. var timeZone = DateTimeZoneProviders.Tzdb["Pacific/Auckland"]; //var timeZone = DateTimeZoneProviders.Bcl["New Zealand Standard Time"]; // Convert the instant to the zone's local time var zonedDateTime = instant.InZone(timeZone); Debug.WriteLine(zonedDateTime); // Local: 7/16/2013 7:29:00 AM Offset: +12 Zone: Pacific/Auckland // and if you must have a DateTime, get it like this var bclDateTime = zonedDateTime.ToDateTimeUnspecified(); Debug.WriteLine(bclDateTime.ToString("o")); // 2013-07-16T07:29:00.0000000
