jc - JSON CLI output utility dig command output parser

Options supported:

The when_epoch calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)

The when_epoch_utc calculated timestamp field is timezone-aware and is only available if the timezone field is UTC.

Usage (cli):

$ dig example.com | jc --dig

or

$ jc dig example.com

Usage (module):

import jc.parsers.dig
result = jc.parsers.dig.parse(dig_command_output)
