<DIV><FONT size=2 face=Arial>Hi,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I am a Delphi programmer and am working on a time
zone problem. In the Olson database I'm having trouble differentiating
between times that are strictly standard and those that include summer time /
daylight savings. Is there a standard in the code for differentiating
these? Most of it is fairly simple to understand but I am mystified by
some of the abbreviations in the rule changes. For instance:</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial># Rule NAME FROM TO TYPE IN ON AT SAVE
LETTER/S<BR>Rule Finland 1942 only - Apr 3 0:00 1:00 S<BR>Rule Finland 1942 only
- Oct 3 0:00 0 -<BR>Rule Finland 1981 1982 - Mar lastSun 2:00 1:00 S<BR>Rule
Finland 1981 1982 - Sep lastSun 3:00 0 -<BR># Zone NAME GMTOFF RULES
FORMAT [UNTIL]<BR>Zone Europe/Helsinki 1:39:52 - LMT 1878 May 31<BR>
1:39:52 - HMT 1921 May # Helsinki Mean Time<BR>
2:00 Finland EE%sT 1983<BR> 2:00 EU EE%sT</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>What is the % symbol I keep seeing in the code
for? For instance, in "2:00 EU EE%sT" is "EE%sT" Eastern
European Standard Time? I take this to mean that Finland is currently on
EU rules with a UTC offset of +2. Every now and then I also find
something like this:</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>"2:00 1:00 EEST 1989 Sep 24 2:00s"</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Does this line mean that I add 1 hour to the 2:00
hours UTC? Or is this correction already included in the 2
hours?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thanks!</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Sincerely,</FONT></DIV>
