Just being doing an AWS EC2 volume enlargement and the output of StartTime is in UTC

aws --profile gap ec2 describe-volumes-modifications --volume-id vol-XXXXXXXXXXXXXXXXXXXXX


    "VolumesModifications": [
            "VolumeId": "vol-XXXXXXXXXXXXXXXXXXXXX",
            "ModificationState": "optimizing",
            "TargetSize": 200,
            "TargetIops": 600,
            "TargetVolumeType": "gp2",
            "OriginalSize": 80,
            "OriginalIops": 240,
            "OriginalVolumeType": "gp2",
            "Progress": 52,
            "StartTime": "2021-01-01T01:06:48+00:00"

What is the local time for the “StartTime” value in the output of the aws cli command

GNU date command

Set the TZ environment variable to your timezone

TZ=Australia/Melbourne date -d "2021-01-01T01:06:48+00:00" -Iseconds
