About
-----

Net Time is a freeware control panel for the IIgs that allows you to
synchronize your IIgs clock with any RFC-868 compliant time server. There
is a default time server provided, but you can easily specify one of your
own.

Requirements
------------

Net Time should work on any IIgs that has Geoff Weiss' Time Tool Set and
Richard Bennett's Marinetti 2.0.1 installed and configured.

Installation
------------

To install Net Time, simply copy the NetTime file to the CDevs folder on
your system drive and reboot. If you do not already have the Time Tool Set
installed, also copy the TimeZone file to the CDevs folder and the Tool056
file to the Tools folder. Or, just drag and drop the files on the System
folder icon, and let the Finder's magic routing put everything in the
proper place.

Using Net Time
-------------

Open the Control Panels NDA and then open Net Time, or double-click on the
NetTime file from the Finder. Enter a time server name or IP address (or
leave it set to the default), and hit the Sync Now button.

If Marinetti is properly connected to the Internet and your Time Zone
setting is correct, your IIgs clock should be synchronized with the time
server's clock. With many time servers on the Internet, but not all, this
should also be quite close to the current atomic clock time.

Currently, you have to manually run Net Time when you wish to synchronize
your IIgs clock. If there is enough interest, version 2 will have the
capability to schedule automatic updates.

Semi-Technical
--------------

Net Time attempts to connect to TCP port 37 on the specified time server,
and if successful, retrieves a 4-byte time value (the current GMT time
offset in seconds since January 1, 1900) . It then uses your time zone
setting to convert this value into the correct local time before setting
the IIgs clock.

With Internet delays and IIgs speed, the time may end up being off by a
second or two, but hey, that's life.

RFC-868 specifies both TCP port 37 and UDP port 37 as valid for this
service, but Net Time only tries to connect via TCP.

Version History
--------------

v1.0 - March 24, 2002
First public release

v1.0.1 - May 4, 2002
Net Time was not correctly checking to see if the IIgs was in Daylight
Savings Time. This would sometimes cause the synchronized time to be off by
an hour. Fixed.
