Keterangan

Rentang waktu yang dikembalikan mencakup perbedaan apa pun karena penerapan aturan penyesuaian ke zona waktu saat ini. Ini berbeda dari BaseUtcOffset properti, yang mengembalikan perbedaan antara Waktu Universal Terkoordinasi (UTC) dan waktu standar zona waktu dan, oleh karena itu, tidak memperhitungkan aturan penyesuaian.

dateTime Jika properti parameter Kind tidak sesuai dengan objek zona waktu, metode ini melakukan konversi yang diperlukan sebelum mengembalikan hasil. Misalnya, ini dapat terjadi jika Kind properti tetapi DateTimeKind.Local objek zona waktu bukan zona waktu lokal. Jika dateTime ambigu, atau jika waktu yang dikonversi ambigu, metode ini menafsirkan waktu ambigu sebagai waktu standar. Jika dateTime tidak valid, metode ini mengembalikan TimeSpan objek yang mencerminkan perbedaan antara UTC dan waktu standar zona waktu.

Metode TimeZoneInfo.GetUtcOffset(DateTime) ini mirip dalam operasi dengan GetUtcOffset metode TimeZone kelas .
