DateTime.Now and DateTime.UtcNow #26

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Two methods have different performance according to
http://www.codeproject.com/KB/cs/DateTimePrecise.aspx?msg=2761979

Stopwatch.GetTimestamp()    0.000000184
DateTime.Now    0.000000226
DateTime.UtcNow     0.000000010
DateTime.UtcNow.ToLocalTime()   0.000000221
DateTimePrecise.Now     0.000000482
DateTimePrecise.UtcNow  0.000000248
DateTimePrecise.UtcNow.ToLocalTime()    0.000000455

226 micro for DateTime.Now and 10micro for DateTime.UtcNow
The difference between two is local time. Should be tested in Linux
