Describe the bug
There is an error when ULS tries to autoresume a ETP DNS feed because it thinks that checkpointed timestamp is unix timestmap but in fact it is still a normal timestamp. Ex: {"creation_time": "2026-01-14 02:55:43.809856", "checkpoint": "2026-01-14T02:26:14Z", "input": "ETP", "feed": "DNS", "current_count": 5672000}

I think we have to remove this line here: https://github.com/akamai/uls/blob/main/bin/modules/UlsTools.py#L282 for this to work.

I tested this locally and that is in fact the problem.

WDYT? I can open a PR if needed as well.
