Training stops due to "botocore.exceptions.ClientError: An error occurred (RequestTimeTooSkewed)"

I've been running local training on a 15" mid 2014 Macbook Pro for about a week. The last two times I started retraining from a pretrained model it stopped after making two checkpoints due to this error:

botocore.exceptions.ClientError: An error occurred (RequestTimeTooSkewed) when calling the PutObject operation: The difference between the request time and the server's time is too large.

Does anybody have tips on resolving?

Full stack track:
