This script should be used when requesting the correct  time  from  an  ntp
server  (time  server).  If an ntp server is queried, it updates the system
time. This script saves this updated time to the battery clock of the Amiga
and optionally creates a logfile to keep track of the correction applied to
the system time.

To  get  an  address  from  an  adequate  ntp  server,  have  a   look   at
''.  Choose  one  and insert
the address into the relevant string  gadget  (bottom  of  'TCP/IP'  page).
Don't forget to activate the 'Get Time' switch.

Then enter the path/name of this script  (e.g.  ARexx/  into
the  'Online' string gadget ('Events' page). This starts the script as soon
as the ntp server transmitted the time information.

Optionally,  the  corrections  applied  to  the  current system time can be
logged to a file. If this is desired, set  the  'log'  variable  to  'true'
(default  is  'true')  and  enter the path/name of the log file (default is

Example of a log file:

Date          old time  ntp time  error

The variable 'secdelta' takes system speed into account and has to  be  set
accordingly.  Fast  systems  use  1 (68060), slow system 2 or 3 (68020). To
find the correct value, run the script a  couple  of  times  with  the  log
option  enabled and analyse the log file. The average of the time errors is
the value to enter here (in seconds).

ENVARC:TZ must be set up correctly as well. Have a look at 'http://www.ifh.
de/computing/manuals/infohtml/glibc/library_318.html'   for   details.  For
Luxembourg, I have "CET-1". For some  reason,  "CET-1CEST-2"  doesn't  work
properly  on  the  Amiga.  Therefore,  I  change TZ manually to "CET-2" for
daylight saving. Apparently, TZ only accepts 3 digits as national time zone
code.  In  fact,  the  3  digits  aren't  used, which means that "xxx-1" or
"xxx-2" would work as well.

The file "tzdata1997a.tar.gz" gives even more detailed information. It  can
be found at "". Here the most important zones.
