+## Set Real Time Clock
+
+This Command Message sets the real time clock to the specified big-endian count of miliseconds since `11-15-2001 00:00:00 UTC`, represented in hex. This code is identical to the original Xbox Real Time Clock (RTC) code.
+
+The maximum value that the clock can be set to is `FFFFFFFFFF`, representing `09/17/2036 19:53:47 UTC`. After this, the clock will wrap around.
