ArcGIS Velocity Feed Time Zone Not UTC

Question

Hello! I've got a feed that is polling a local server including timestamps in CST central time and Velocity is assuming they are UTC and and then map viewer is displaying them -6 hours trying to correct for CST. The time zone is not included in the time stamp from the source in the API.

"yyyy-MM-dd'T'HH:mm:ss.SS"

What is the best way around this? I'm currently pushing a feed to a ArcGIS Velocity layer watching the TRACK_ID to keep only new features each push.

Thanks!!

@Teresa_Blader Thanks for posting, I agree with @JeffSilberberg that the methods to utilize would be either ChangeTimeZone() https://developers.arcgis.com/arcade/function-reference/date_functions/#changetimezone or DateAdd() https://developers.arcgis.com/arcade/function-reference/date_functions/#dateadd

Velocity is assuming UTC on ingestion by design but that is something we could consider for a future release to add user timezone parameter specification for string date parsing to adjust to UTC under-the-hood which is what is primarily utilized for IoT/real-time monitoring.

Thanks for the response @PeterNasuti and @JeffSilberberg

I may be incorrectly assuming the API is pushing CST, so I'll verify - but I'm going to keep those in mind and give those a try!
