OPC Relative Time Format

Enter a time value that is relative to the present time, by entering the value in the OPC Relative Time Format.

You use the OPC Relative Time Format, for instance, to enter Trend offsets.

If you are required to specify a relative time, either:

• Use the browse button next to the field to display an Offset window. You can then use the window to specify the required relative time value (see Offset Window).

  or:

• Enter the relative time directly in the field (see Specify a Relative Time in the OPC Relative Time Format).

  To specify a relative time that always refers to a time in the past, or that takes into account a particular time zone, see Specify a Relative Time that Always Refers to a Time in the Past.
