Public ReadOnly Property ServerTime As AFTime
	Get

Dim instance As PIServer

Property Value

Type: AFTime
Returns the current time of the PI Data Archive if connected to the server. Otherwise, MinValue is returned.

Implements

IAFTimeSourceServerTime

Remarks

The property will cache the server time bias, and will not re-retrieve the server time on every call. It will periodically check against the server and recompute the time bias. If you wish to force a re-check of the server bias, call Refresh.

Notes to Callers
This property returns an AFTime, which represents the server time in Coordinated Universal Time (UTC). The property AFTime.LocalTime will convert the UTC Time to the local client time zone, which may be different than the server time zone. To see the time as the local time in the server's timezone, use the following command (where 'server' is the PIServer or PISystem object): server.ServerTimeZone.ToLocalTime(server.ServerTime).
