This is useful. Here's some feature creep: Since the timestamp output is configurable, there is no need to settle on one specific timestamp format. The option could allow a choice between MONOTONIC and REALTIME, with an option for REALTIME to include the date in ISO 8601 format (YYYY-MM-DD). And REALTIME could be UTC or local time. You could consider taking a format string for strftime(), with the extension that %f expands to 6 digit microseconds like in Python [1].
