--timestamp customization (format string like in UNIX date or GNU date)

Feature Request

• When using the --timestamp option it would be great if one could customize the format.
• Ideally a well known/supported syntax, such as the one of the date utility.
• If you'd implement it, I propose the following:
  • --timestampalone uses the default timestamp format
  • --timestamp <format-string> uses the custom date/time-stamp, e.g.
  • --timestamp '+%Y-%d-%m %H:%M:%S'
  • --timestamp plus argument --rfc-email or --rfc-3339=FMT anywhere else in command line to use these standardized date/time-stamp-formats (as in gnudate)

Any plans for implementation?
