Has any one had really slow services when setting the timezone to something other than UTC?

I have created three feature services that get updated every hour and one has over 30,000 features.  When I set the timezone in the service parameter to PST since the date/time field is in PST the web service is super slow to load if at all.  When I don't set the timezone the map service is fast.  Is there a particular date/time format that ArcGIS Server/Enterprise is looking for to speed things up?

Yes!! I’m having this same issue right now. Did you ever find a solution or workaround? It’s unusably slow when I set it to the correct time zone.
