Specify time zones

The AVEVA™ PI System™ can usually determine whether daylight saving time is in effect. If you wish to be specific, then use the DD-MMM-YY hh:mm:ss.ssss fixed time format and append the time zone.

PI supports both long time zone names (such as Pacific Standard Time) and short time zone names (such as PST). You can specify either name. Comparisons are not case sensitive. The following time strings are equivalent:

25-Oct-98 01:30 Pacific Daylight Time
25-Oct-98 01:30 pdt
25-Oct-98 01:30 D

Other commonly used time zone codes include S for standard time, D for daylight time, and MET for Middle European Time.
