'time' is RFC 868, a pre-NTP time synchronization protocol. It just
sends the time as a 32-bit int, where:
"The time is the number of seconds since 00:00 (midnight) 1 January 1900
GMT, such that the time 1 is 12:00:01 am on 1 January 1900 GMT; this
base will serve until the year 2036."
I think it sends it big-endian, but I'm not sure.
