How long is a .NET DateTime/TimeSpan tick?

How long is a .NET DateTime/TimeSpan tick?

Solution 1:

Although currently a tick is 100 nanoseconds, it is best not to rely on this as an absolute. Rather, use 'TimeSpan.TicksPerSecond' (or any of the other TicksPerXxx member values)

Solution 2:

The tick is the unit of granularity for the .NET DateTime and TimeSpan value types.

It has the following common conversions:

1 tick = 100 nanoseconds
       = 0.1 microseconds
       = 0.0001 milliseconds
       = 0.0000001 seconds

Solution 3:

To quote MSDN:

The smallest unit of time is the tick, which is equal to 100 nanoseconds.

Metrology fail.
