Field	Description
Use Time	During boot procedure the P201 can connect to a time server to calibrate its system clock.
Server when	You can choose which time protocol is preferred. Toggle and select Daytime (RFC-867);
Bootup	Time (RFC-868), NTP (RFC-1305)or None. The former two protocols use TCP protocols
	and the third one uses UDP protocol.
	The main differences between them are the format, e.g., the Daytime (RFC 867) format is
	day/month/date/year/time zone of the server while the Time (RFC-868) format gives a 4-byte
	integer giving the total number of seconds since 1/1/1970 at 0:0:0. The NTP (RFC-1305)
	format is similar. Not all timeservers support all protocols, so you may have to check with
	your ISP/network administrator or use trial and error to find a protocol that works. If you select
	None (this is the default value), you can enter the time manually but each time the system is
	booted, the time & date will be reset to: 1/1/1970 0:0:0
Time Server	Enter the IP address of the selected time server. If you choose None then this field is N/A.
IP Address	once you assign an IP address of a time server (e.q. an UNIX server), then the Prestige will
	get the date, time, and time-zone information from this server.
New Time	Enter the new time of the place where the P201 is located in hour, minute and second format.
New Date	Enter the new date of the place where the P201 is located in year, month and, date and
	format.
