Epoch miliseconds to date

[ggregor_pulsiam]

Hi, I have multiple date fields as epoch miliseconds with a Big integer data type.

I would like to convert these to a new field which has Date data type.

I tried multiple things I couldn't figure out what I am doing wrong, I am seeking for some help.

I have been trying to convert them in ArcGIS Pro.

Thank you in advance

The Arcade function Date will correctly interpret epoch milliseconds. Just do a field calculation:

Date($feature['calldate'])
