Daylight! 4.03 is a Daylight Saving Time adjustment Extension. It makes the time changes from year to year for you without you having to worry about it.
To install:
---------
Daylight! belongs in the Control Panels folder inside your System Folder. Drag Daylight! 4.03 on top of your System Folder or on top of or into your Control Panels Folder. Delete any older versions of Daylight!. Ensure that your Mac has the correct local time. Open the Daylight! Control Panel and set the dates and ensure the "Now in DST" check box is correct. Close the Control Panel and restart your Mac.
REVISION HISTORY:
Version 4.03:
• Added function to change the Parameter RAM's GMT offset when DST adjustments are made. Many thanks to Pete Resnick for helping me get this right.
Version 4.02:
• Fixed a bug which caused a minor incompatibility with Microsoft Mail. Thanx to Paul Galanti and Peter Kaufman for helping me out.
• Changed start/end date computation such that if DST starts late in the year and ends early the next year, the dates are correct. This is for our friends in the Southern Hemisphere. Thanx to Sean McNamara for pointing this out to me.
• Changed the way the Control Panel acts toward the "Now In DST" checkbox. Now it always reflects the DST state based on the dates, and cannot be changed most of the time. The only time it can be changed is during the repeated hour on backward adjustments, just in case you're setting this thing up during that hour. Also changed ballooon help on the check box to say this.
• Removed references to "spring" and "fall" and replaced them with "DST begin" and "DST end". Probably was OK, but this will avoid any possible confusion in case someone's DST doesn't begin in the spring or end in the fall.
Version 4.01:
• Added support for the Daylight Saving Time bit in the parameter RAM that I just found out about. This is a great fix because now it doesn't matter if you boot from different drives - the computer's PRAM knows if you're in DST or not. Works fine with a Plus, which surprised me.
• Changed the wording in a dialog to make it a little more clear.
Version 4.0:
• Daylight! is now FREE. But see appeal in the Control Panel.
• Nearly a total rewrite of the Control Panel using my generalized object-oriented framework for Control Panels and dialogs.
• New look for the Control Panel.
• Added balloon help for the Control Panel.
• Removed documentation file from upload.
• Dropped support for System 6. (sorry)
• If you have the Control Panel up 2 minutes before a time change, you get a warning that you'd better close it.
• If you have the Control Panel up at the time change, you get a message saying your changes have been lost.
• Changed my address. I don't plan to move again any time soon.
• Dropped the Time Zone hack.
• Probably lots of other things that I can't think of now.
Version 3.33:
• Made display of dates, days, and months conform to International systems.
• Modified the TEXT/styl resource to read a little better to international users.
• Generally cleaned up some things.
Version 3.32:
• Never released.
Version 3.31:
• Changed the address in both the documentation and the Control Panel. Thank you, Mail Boxes, Etc., for skipping town without warning AND trying to soak me for another three months rental fee just before leaving. Hope I can return the favor someday.
Version 3.3:
• Fixed problem which rendered earlier versions to bomb under System 7 in 32-bit mode (oops).
• Changed a dialog very slightly.
Version 3.21:
• Released with later v3.1 disks
• Fixed a bug in v3.2 which caused problems with other Extensions which installed GetNextEvent filters BEFORE Daylight! loaded.
Version 3.2:
• Released with v3.1 as a hack.
• Added a feature which allows entry of time zones and option to append time zone abbreviation to the time of day.
Version 3.1:
• Initial public release.
Version 3.0:
• Initial swipe at real-time time adjustment.
Version 2.0:
• Shareware release of long ago which adjusted time only at startup.
