Time Series chart from a calculated Time And Date attribute.

I’m getting some data from a REST. The date and time returned is a Linux style integer which I’m converting into a human readable value and storing in a calculated attribute by the means of a microflow. Trying to use the calculated date and time as the X axis of a time series chart, what I have is just the chart gets stuck forever. Any fix or workaround other that store the attribute instead of calculate it?

Can you just calculate it as part of your microflow that gets the data from the REST service and commit it then? It removes the need from having to use a calculated attribute.
