* Formats date and time like strftime (but with timeval structure as input)
* and adds extra specifiers:
* - "%@": return the date expressed in Coordinated Universal Time (UTC)
* instead of date relative to the user's specified timezone
* - "%.1" to "%.6": first N digits of microseconds, zero-padded
* - "%f": alias of "%.6" (microseconds, zero-padded to 6 digits)
* - "%!": timestamp as integer, in seconds (value of tv->tv_sec)
