JQ - Using a non UTC date field and looking back a certain amount of time

I am trying to write a BASH+jq one liner to only return the entries that are less than 5 minutes old as I am writing automation to only look back 5 minutes (BASH). Using the following JSON:

[  {"id": 621024,"iid": 99999,"project_id": 999,"sha": "faf897sd98fa987afsd98f7","ref": "master","status": "running","source": "push","created_at": "2024-05-10T16:32:01.072-04:00","updated_at": "2024-05-10T16:32:03.565-04:00","web_url": "https://gitlab/pipelines/9999","name": null  },  {"id": 621023,"iid": 99999,"project_id": 999,"sha": "faf897sd98fa987afsd98f7","ref": "master","status": "success","source": "push","created_at": "2024-05-10T16:31:47.951-04:00","updated_at": "2024-05-10T16:35:30.362-04:00","web_url": "https://gitlab/pipelines/9999","name": null  },  {"id": 621020,"iid": 99999,"project_id": 999,"sha": "faf897sd98fa987afsd98f7","ref": "master","status": "waiting_for_resource","source": "push","created_at": "2024-05-10T15:27:00.248-04:00","updated_at": "2024-05-10T15:30:14.172-04:00","web_url": "https://gitlab/pipelines/9999","name": null  },  {"id": 621019,"iid": 99999,"project_id": 999,"sha": "faf897sd98fa987afsd98f7","ref": "master","status": "success","source": "push","created_at": "2024-05-10T14:26:02.235-04:00","updated_at": "2024-05-10T14:29:45.406-04:00","web_url": "https://gitlab/pipelines/9999","name": null  }]

My challenge is that the date being returned for created_at is in EST

I have been trying to use some of the traditional time functions/tools with jq but dont think its working because they expect the date to check against to be in UTC

I know I can take off the milliseconds using something like

jq '.[] | .created_at |= .[0:19]'

But that still leaves me with a timestamp that is in EST.

"created_at": "2024-05-10T15:27:00"

All the documentation I read talks about needing the date to be in ISO 8601 to be parsable with some of date/time functions. I dont know what to add to my jq that would subtract only selecting the entries that are less than 5 minutes old

This query fails:

jq '.[] | .created_at |= .[0:19] | select(.created_at | fromdate - 300)'

with error

jq: error (at <stdin>:55): date "2024-05-10T16:32:01" does not match format "%Y-%m-%dT%H:%M:%SZ"
