Formatting Dates in Operations Dashboard Serial Charts

[EvanTimms]

I am currently working with a serial chart in Operations Dashboard, viewing USGS Earthquake data by Magnitude for All Events - it is a map service. I have the data on Categories From: Features, based on Event Time (which in the data table looks to be formatted: MM/DD/YYYY, HR:MM:SS ex. 2/19/2020, 11:01:01 AM). This is how I want the data to appear in my chart category labels, but it brings up GMT-0800 (Pacific Standard Time) at the end of the label. 

I want to format the labels so that it displays everything up to but not including GMT.

Thanks!
