Timesync uses the following SET parameters. For more information, see NW 6.5 SP8: Utilities Reference.
Parameter |
Explanation |
---|---|
start of daylight savings time = date_and_time |
Local date and time when the switch onto daylight savings time should occur. Formats include a simple date and time or rules introduced by an parentheses "( ". For example: April 4 1993 2:0:0 am, (April 4 2:0:0 am), (April Sunday <= 1 2:0:0 am), or (April Sunday First 2:0:0 am). Only rules can reschedule for the next year. You must set both the start and end dates before either will be scheduled. |
end of daylight savings time = date_and_time |
Local date and time when the switch off of daylight savings time should occur. Formats include a simple date and time or rules introduced by an open parentheses "( ". For example: October 31 1993 2:0:0 am, (October 31 2:0:0 am), (October Sunday <= 31 2:0:0 am), or (October Sunday last 2:0:0 am). Only rules can reschedule for the next year. You must set both the start and end dates before either will be scheduled. |
daylight savings time offset = [+|-] hour:minute:second |
The offset applied in time calculations when daylight savings time is in effect. The default is +1:00:00 (one hour). Issuing this command causes UTC time to be recalculated from local time. Default: +1:00:00 |
timesync configured sources = on|off |
When On, this server does not listen to advertising time sources. Instead it only contacts sources explicitly configured with the Time Sources parameter. Default: Off |
timesync polling count = number |
Specifies the number of time packets to exchange while polling with the time provider. Default: 3 |
timesync polling interval = number |
Specifies when the next polling is scheduled. Default: 600 |
timesync reset = on|off |
When set to On, Timesync resets the selected internal values and clears the configured server list. The flag automatically sets to Off. Default: Off |
timesync restart flag = on|off |
When set to On, Timesync will restart. The flag automatically resets to Off. Default: Off |
timesync service advertising = on|off |
When On, this time source advertises itself using SAP/SLP. Secondary time servers never advertise. Default: On |
timesync synchronization radius = value_in_milliseconds |
Specifies the maximum tolerance. Timesync remains in synchronization while the offset is lesser than this value. Default: 2000 |
timesync time adjustment = [+|-]hour:minute:second[at month/day/year hour:minute:second [AM or PM]] |
Schedule a time adjustment. Can only be issued from a Single, Reference, or Primary type server. The format is [+|-]hh:mm:ss [AT [date and time]]. Default date and time is six polling intervals or one hour (whichever is longer) from now. Using the word CANCEL instead of a date to cancel a previously scheduled adjustment. Single and Reference time servers do not accept adjustments from Primary time servers. Default: None scheduled |
timesync time source: IP_address |
This server contacts the servers in this list as time providers. Each time server (IP address, DNS Name) in this list is separated by a semicolon ( ; ). For example: a semicolon ( ; ) clears the list MyServer and specifies that MyServer is the NetWare time source. MyServer:123; specifies that MyServer is a NTP time source. Default: Empty list |
timesync type = primary|single|reference|secondary |
Specifies the Timesync server type: Single, Reference, Primary, or Secondary. Default: Single |
timesync max log file size = number |
Specifies the largest size in kilobytes of the SYS:\SYSTEM\TIMESYNC.LOG file. Range: 500 to 1,073,741,824 |
standard time offset time zone = IST [Time offset from IST] |
Enter the offset in hours from Universal Time Coordinated (UTC). Time zone string indicates the abbreviated name of the time zone, the offset from UTC, and the alternate abbreviated time zone name to be used when daylight savings time is in effect. The default is <>. Issuing this command causes UTC time to be recalculated from local time. Default: Selected during installation |
default time server type = primary|single|secondary|reference |
Specifies the default time synchronization server type. Choose from Secondary, Primary, Reference, or Single. This parameter can be overridden by separate time synchronization parameters. Default: Secondary |
debug flag = 0|7|15 |
Specifies whether Timesync opens or logs a debug screen to view or log debug information. To enable the debug screen and log it to timesync.log (located in sys:\system): set timesync debug=15 To enable the debug screen only and disable the log: set timesync debug=7 To disable both the debug screen and logging: set timesync debug=0 For more information about advanced usage of debug flag, see Advanced Usage for Debug Flag. |
Timesync debug screen information is logged into the sys:\system\timesync.log file. The following table displays the usage of debug flag:
Setting the time backwards is not recommended for the following reasons:
Impacts eDirectory drastically, as synchronizing of objects across eDirectory is dependent on timestamps.
eDirectory considers this as synthetic time.
To ensure consistent timestamps across eDirectory, DSREPAIR.NLM provides an interface to declare a new epoch. This results in very high traffic to restamp all eDirectory objects.
The standard practice, before starting a NetWare server, is to ensure that the time is as close as 10 minutes to the network time. This prevents many time synchronization issues.
