     <Description>This pre-release alpha package provides timestamps in a similar manner to DateTime.Now except it uses the hardware's high precision event timer, where available.  Time stamps are more precise and, when retrieved on the same thread within a short time of each other, can be expected to be more accurate relative to each other than those retrieved by DateTime.Now.  They may be less accurate in reference to offical UTC time or system time, but, under most circumstances, should remain approximately accurate.
 
 The use-case for this project is when approximately accurate timestamps are needed for purposes of identifying when an event happened, but are also used to measure elapsed time between events that happen on a scale of milliseconds or microseconds.</Description>

+Focus is now on the monotonic stamps.
 
 Added a duration type analogous to TimeSpan but matching the frequency of stopwatch rather than timespan.  This allows computations to be made without rounding errors.  duration's backing field will probably be changed to a Int128 once I find one written in a relatively modernish style of C# that will not require massive importation of dependencies.   The problem was detected when testing on a linux machine where the stopwatch frequency was 1,000,000,000 rather than 10,000,000 as in windows -- adding a timespan to produce new stamp and then subtracting same produced distinct values due to round-off.
