If `dueTime` is zero (0), `callback` is invoked immediately. If `dueTime` is <xref:System.Threading.Timeout.Infinite?displayProperty=nameWithType>, `callback` is not invoked; the timer is disabled, but can be re-enabled by calling the <xref:System.Threading.Timer.Change%2A> method.

Because the <xref:System.Threading.Timer> class has the same resolution as the system clock, which is approximately 15 milliseconds on Windows 7 and Windows 8 systems, the `callback` delegate executes at intervals defined by the resolution of the system clock if `period` is less than the resolution of the system clock. If `period` is zero (0) or <xref:System.Threading.Timeout.Infinite?displayProperty=nameWithType> and `dueTime` is not <xref:System.Threading.Timeout.Infinite?displayProperty=nameWithType>, `callback` is invoked once; the periodic behavior of the timer is disabled, but can be re-enabled using the <xref:System.Threading.Timer.Change%2A> method.
