Open Internet Time Protocol (OITP)

This document specifies the Open Internet Time Protocol (OITP), a network time synchronization protocol for decimal time systems that divide the civil day (86400 SI seconds) into 1000 primary units called beats, each exactly 86.4 SI seconds. OITP enables clients to synchronize decimal time clocks over packet-switched networks with sub-beat precision, using techniques derived from existing network time protocols adapted for the decimal time domain. The reference timescale uses UTC+1 as its reference meridian, with midnight at UTC+1 corresponding to beat zero.
