Incorrect date format for processed_time field from the Export API

Is anyone else seeing incorrectly formatted timestamps from the Export API? This is causing an error for a script I have that calls that API.

The issue I’m seeing is that events roughly with a processed_time value that’s between 2022:05:27 01:02:50.047099 and 2022:05:27 11:28:48.569078 do not have that field in ISO-8601 format. An example of the format I would expect is 2022-05-27T00:27:49.773Z.

From the Export API documentation, it’s stated that that field should be an “ISO-8601 formatted timestamp.” which means the year, month, and day should be separated by a hyphen.


Any help from the Amplitude support team would be much appreciated.
