Server Time displays the current date & time of the monitor which is getting monitored along with its Time Zone.
Time Difference calculates the amount of minutes that differs between the APM Server Time and the monitoring server time(i.e, absolute difference between the monitoring server time and the APM Server Time in minutes)
To get the Current Time of the servers we use uptime.vbs script which is located under the <APPMANAGER_HOME_DIR>/working/conf/applications/scripts/
