TimeZone 類只識(shí)別本地時(shí)區(qū)，但可以在協(xié)調(diào)世界時(shí) (UTC) 和本地時(shí)間之間轉(zhuǎn)換時(shí)間。TimeZoneInfo 對(duì)象可以表示任意時(shí)區(qū)，且 TimeZoneInfo 類的方法可用于將一個(gè)時(shí)區(qū)的時(shí)間轉(zhuǎn)換為其他任意時(shí)區(qū)的相應(yīng)時(shí)間。

TimeZoneInfo timeZoneInfoLocal = TimeZoneInfo.Local;
        string s = timeZoneInfoLocal.DaylightName + "," + timeZoneInfoLocal.DisplayName + ","
            + timeZoneInfoLocal.Id + "," + timeZoneInfoLocal.StandardName + "," + timeZoneInfoLocal.SupportsDaylightSavingTime;

        //獲取本地時(shí)間對(duì)應(yīng)的標(biāo)準(zhǔn)時(shí)間(UTC)
        DateTime utc=TimeZoneInfo.ConvertTimeToUtc(DateTime.Now);
        //UTC轉(zhuǎn)化為本地時(shí)間
        DateTime nowTime = TimeZoneInfo.ConvertTimeFromUtc(utc, timeZoneInfoLocal);

        //獲取本地時(shí)間和UTC之間的差值--時(shí)差
        TimeSpan utcOffset =TimeZoneInfo.Local.BaseUtcOffset;
        TimeSpan utcOffset1 = TimeZoneInfo.Local.GetUtcOffset(DateTime.Now);

        TimeSpan a = new TimeSpan(10, 0, 0);

        TimeZoneInfo timeZoneInfoHawaiian = TimeZoneInfo.CreateCustomTimeZone("Hawaiian Standard Time sss", a, "夏威夷", "Hawaiian");
        DateTime hawaiianTime = TimeZoneInfo.ConvertTimeFromUtc(utc, timeZoneInfoHawaiian);
