Table 80   System Maintenance: Time and Date Setting

Time Protocol

Enter the time service protocol that your time server sends when you turn on 

the ZyAIR. Not all time servers 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. The main differences between them are the format. 
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC-868) format displays a 4-byte integer giving the total number of 

seconds since 1970/1/1 at 0:0:0. 
NTP (RFC-1305) is similar to Time (RFC-868).
None. The default, enter the time manually.
