What format is the timestamp in the notify component

Configuration
1

I want to do some data analysis of a sensor output, so I am using the notify component to record the sensor data to a file. One option of the notify component is to put a timestamp on each entry.
What format is the timestamp and does anyone have a clue how to decode it in Excel?

2022-04-22T22:18:09.462129+00:00 453.35
2022-04-22T22:18:40.768944+00:00 453.35
2022-04-22T22:19:49.480535+00:00 457.0
2022-04-22T22:21:29.489775+00:00 458.56
2022-04-22T22:23:09.473489+00:00 450.65

Thanks.

Standard iso timestamp.
