Depending on the runtime system, the real time clock (RTC) of the controller is provided in standard or high resolution time stamp. That is, the time stamp represents the seconds (standard resolution) or milliseconds (high resolution) since January 1st, 1970 00:00:00. It is also known as UNIX format.
The RTC in standard resolution is supported for all EcoStruxure Machine Expert controllers. Refer to the table in the Document Scope chapter to verify for which controller supports the high resolution RTC.
