today I want to shre small note of how to generate timestamp for Acumatica objects ( in case if you use for some reason PXDataBase.Insert or PXDataBase.Update)
PXDataBase has public method SelectTimeStamp.
public static byte SelectTimeStamp()
So, in case if you need to put in variable t TimeStamp you can do the following:
var t = PXDatabase.SelectTimeStamp();
And variable t will have timestamp
