I see Andy gave an example of this ...

Look in /usr/local/epics/<RELEASE>/base/include/tsDefs.h for time
stamp utilities such as ...

 TsAddStamps(pSum, pS1, pS2)
 TsAddDouble(pSum, pS1, dbl)
 TsDiffAsDouble(pDbl, pS1, pS2)
 TsDiffAsStamp(pDiff, pS1, pS2) 
 TsCmpStampsEQ(pS1, pS2)
 TsCmpStampsNE(pS1, pS2)
 TsCmpStampsGT(pS1, pS2)

 etc ...
