Is there any way to post events custom time stamp to New Relic using nri flex?

Is there any way to post custom time stamp to newrelic? I am using integration.yml file and command api to run shell script command to post the event metrics . With “file api” like below i am able to post custom timestamp with in 48 hours. With “command api”, I am able to post the timestamp with in 24 hours range. I am looking for solution to post the timestamp with in 48 hours using command api . Any suggestions please.

integration.yml with file api:

integrations:

  • name: nri-flex
    config:
    name: sample
    apis:
    - name: sample
    file: /path/to/sample.csv
    to_lower: true
    rename_keys:
    ^timestamp$: timestamp1
    ^timestamp_derived$: timestamp
    remove_keys:
    - timestamp1
    timestamp_conversion:
    timestamp: TIMESTAMP
