I have created a Querytag to access my SQL database.
Tag name = Time.
Data Type = DateTime
Scan Class runs every second.
SQL Query is:
In the Database Query Browser, it gives me the UTC time in 0.034 secs.
I have tried this with 4 different databases. Remote / Local.
But the tag runs fast… I mean seconds are sometimes milliseconds.
It gets up to 4 hours fast, then bounces to near the correct time.
Query load is 1.2 queries/sec.
