[feature request] start time, end time, category duration

[nextgen-networks]

Hey great script!

Is it possible to add some extra time/duration data to the results?
That would it ease to utilise the results for tickets/servicerequests for service providers and their suport teams.
They would be enabled to compare the perfomance data with their logs at specific time stamps

possible data could be:

• start date & time (human readable & linux timestamp)
• end date & time (human readable & linux timestamp)
• category duration (ms/s/m/h)

Thanks! :-)
