Common questions

How do I convert ticks to a DateTime in C#?

new DateTime(ticks, DateTimeKind.Utc), or paste the value above if you just need to read one. Note that Ticks alone carries no timezone; .NET's Kind property is separate, so know whether your value was recorded as UTC or local.

How do ticks relate to a Unix timestamp?

Unix seconds = (ticks − 621355968000000000) ÷ 10,000,000. That constant is the tick count at the Unix epoch, January 1, 1970.

Why is my ticks value 18 digits when epoch nanoseconds are 19?

Ticks count from year 1, not 1970, but in units of 100 ns rather than 1 ns, and the two effects nearly cancel. That's what makes the two formats so easy to confuse. A 2026 date is ~638×10¹⁵ ticks but ~1.7×10¹⁸ epoch nanoseconds.
