Hello guys

I use tag logging to archive several tags, such as “AI_001_PV, …, AI_009_PV ”. the acquisition cycle is 1 second for these tags in the ProcessValue Archive.

I want to export some archive data to excel use provider, and the timestep in the query statement I set is 5 minutes, the command string is like this: 

TAG:R,'ProcessValueArchive\AI_005_PV','2019-07-04 07:28:18','2019-07-04 08:25:59','TIMESTEP=300,257'

But time interval of the exported data is 1 second!

This is not occur on all the tags, but only for several tags. And it’s not for all the time, but only for several certain time.

For example, when I want to export tag “AI_002_PV”, how often the timestep I set, the result is always correct!

when I want to export tag “AI_005_PV”, sometimes like the time between '2019-07-03 12:25:18' and '2019-07-03 13:20:59' ,how often the timestep I set, the result is also correct; but sometimes like the time between '2019-07-04 07:28:18' and '2019-07-04 08:25:59' ,time interval of the exported data is always 1 second!

The time above is UTC time.
