Thanks, Jim. However, I'm not totally sure this will really help me,
as I'm not really having a problem with daylight savings. The dates
I'm dealing with are entered by the user. They are not gotten from
the computer's clock. All I am doing is converting these dates to
seconds, which is where the problem lies. Or does that conversion
process rely on the computer's clock being accurate? Doesn't seem
like it should. And like I said, some dates convert correctly.
Do you recall if there was specific mention of a problem like this in
the discussion you mentioned? If so, I'll spend a little more time
searching the archives, but I'm not totally convinced that discussion
relates in this case.
Thanks,
Chris

If you look in the archives, this topic was recently discussed
fairly well.
The operating systems do date and time and daylight savings
differently.
This is inherent in each system. If these calculations are
critical to your
operation, you should invest a bit of time building a small date-time
library to add to your distribution.
Hopefully you will find all the data you need to answer your
questions,
especially if you are going to rely on the users computer settings
as being
accurate and in their time zone.
Look at the automatic daylight savings time adjustment for each
operating
system, and in other countries, see which day this is invoked.

This is one for those of you developing for both Mac and Windows. I'm
running into a very strange problem, and I'm not sure if it's a Rev
bug or if it has something to do with hardware differences between
Macs and PCs.
Here's a code snippet:
put "01/06/2006" into tDate
convert tDate to seconds
put tDate
Run this in the message box on both a Mac and a PC. See the different
results. Anyone know why this would happen? What I'm ultimately doing
is converting two dates to seconds and then calculating the number of
weeks that have passed between the two dates. I discovered that my
calculations were incorrect on the PC, and my debugging led me to
this. The value on the Mac seems to be the correct one. What's
strange is some dates seem to be correct when converting to seconds,
but others are not. Try "04/28/2006" for example. Converting to
seconds results in the same value on both platforms.
Can anyone help with this? Or does anyone have another way of
calculating the number of weeks between two dates without converting
to seconds first? Have I found a bug I need to report?
Thanks,
Chris
