Time zone format for diagnostic data

All diagnostic data have a date/time component. The system sends diagnostic time information embedded in diagnostic strings or info. This allows the client to show the time in the selected format.

You can view the current time zone component of the date/time stamp or set it by selecting one of the three available formats from the Time Zone menu, located on the menu bar. The Time Zone menu is available when you select the OI Server Manager or any branch under it in the hierarchy.

The time zone formats are as follows:

• UTC (Coordinated Universal Time): The date/time is shown as per the UTC time of the Communication Driver.

• Client Time Zone: The date/time shown reflects the client’s time zone (that is, Communication Driver UTC + client time zone).

• Server Time Zone: The date/time shown reflects the Communication Driver’s time zone (that is, Communication Driver UTC + Communication Driver time zone).

Another characteristic of time data associated with diagnostic data is related to the duration of the existence of the data. These characteristics are shown in three formats as follows:

• Short-lived data: Used for time stamping data points of end devices (for example, PLCs, RTUs, and control processors). This format shows hours, minutes, and seconds.

• Medium-lived data: Used for transaction start and end times. This format shows month, day, year, hours, minutes, and seconds.

• Long-lived data: Used for the Statistics diagnostic node for the Communication Driver start time and current time. This format shows the day of the week, month, day, year, hours, minutes, and seconds.
