The library has one public clientaction and one public serveraction. These actions can be used to log messages just you would do with LogMessage
The ExtendeLogMessage action returns CurrentDateTimeLog as output parameter. This is the DateTime the log message was stored.
The CurrentDateTimeLog paraneter can be passed to a second optional parameter PreviousDateTimeLog. If you do so, the time between the two dates will be calculated and added to the log message.
