The Millisecond Time Stamp IE is coded as shown in Figure 8.119-1. Octets 5 to 10 represent a 48 bit unsigned integer in network order format and are encoded as the number of milliseconds since 00:00:00 January 1, 1900 00:00 UTC, i.e. as the rounded value of 1000 x the value of the 64-bit timestamp (Seconds + (Fraction / (1<<32))) defined in clause 6 of IETF RFC 5905 [53].
