Subject: [PATCH] Update Timer.xml

When providing the period value as a TimeSpan in ticks, the value must represent at least 1 millisecond. Any value below will be rounded down to zero (0) and the callback is called only once.

 ## Remarks  
  The callback method is invoked once after `dueTime` elapses, and thereafter each time the time interval specified by `period` elapses.  
+ 
+ If `period` value is provided in ticks, they have to be greater or equal to 1 millisecond. A tick value below 1 millisecond will be rounded down to zero (0).
   
  If `dueTime` is <xref:System.TimeSpan.Zero?displayProperty=nameWithType>, the callback method is invoked immediately. If `dueTime` is <xref:System.Threading.Timeout.InfiniteTimeSpan>, the callback method is never invoked; the timer is disabled, but can be re-enabled by calling <xref:System.Threading.Timer.Change%2A> and specifying a positive value for `dueTime`.
