* Formats date and time like strftime and adds additional formats for support
* of microseconds: "%.N" where N is an integer between 1 and 6: first N
* digits of microseconds (for example "%.3" is milliseconds, on 3 digits).
* Format "%f" is an alias of "%.6" (microseconds, zero-padded to 6 digits).
* Formats date and time like strftime (but with timeval structure as input)
* and adds extra specifiers:
* - "%.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)
