[C#] 유닉스 타임스탬프 변환 (Unix timestamp conversion in C#)

New methods have been added to support converting DateTime to or from Unix time. The following APIs have been added to DateTimeOffset:

• static DateTimeOffset FromUnixTimeSeconds(long seconds)
• static DateTimeOffset FromUnixTimeMilliseconds(long milliseconds)
• long ToUnixTimeSeconds()
• long ToUnixTimeMilliseconds()

So .NET 4.6 gives us some new methods, but to use them, you’ll first have to convert from DateTime to DateTimeOffset. First, make sure you’re targeting the right version of the .NET Framework:

You can then use the new methods:

1 2 3

var dateTime = new DateTime(2015, 05, 24, 10, 2, 0, DateTimeKind.Local); var dateTimeOffset = new DateTimeOffset(dateTime); var unixDateTime = dateTimeOffset.ToUnixTimeSeconds();

…and to change back…

1 2	varlocalDateTimeOffset = DateTimeOffset.FromUnixTimeSeconds(unixDateTime)         .DateTime.ToLocalTime();
