Applescript no longer steps through iCal events in sequence

Question

Hi all,
I have been using an Applescript that someone on this forum helped me write a few years ago to put unique combos of events into iCal and it has worked perfectly for me, although this year it has begun to jump around within iCal when it is adding events. In other words it used to step through the calendar and add events day by day, progressing chronologically. Now it still accomplishes the task but starts (currently) with May 1 of 2011 and moves to May 16th ... The fact that it still works is cool, but it has slowed the applescript down quite a lot.
Here is a section of the script...thanks, dan

set cycleday to summary of theEvent
set cycleDate to (start date of theEvent) + 1 * hours
set cycleNumber to last character of cycleday as integer
--There are always 7 periods in every day
repeat with periodNumber from 1 to 6
--Gets the subject from periodCycle
set theSummary2 to item periodNumber of item cycleNumber of periodcycle2
set theSummary to item periodNumber of item cycleNumber of periodCycle
--Checks to see if there's a subject for this period, if not skips to next one
if theSummary2 is not "" then
set theStart to date (startTime of item periodNumber of periodTimes) of cycleDate
set theEnd to date (endTime of item periodNumber of periodTimes) of cycleDate
--Makes the event in the calender whose name is defined at the top of the script
make new event at end of calendar TargetCalendar with properties {summary:theSummary, start date:theStart, end date:theEnd}
end if
end repeat
end if
end repeat </pre>

Hi Bernard,
right, I believe you were the one that came up with this script! It still does the trick, although it does begin adding new events at different times depending on when the cache was last deleted (i think). I've used the Onyx program to do this and indeed it influences the start date for the creation of new events via your script, so I don't think it has anything to do with the master calendar. Since I repeatedly run this script to make new events and then export the calendar, delete it, make a new untitled calendar and then run the script again... I've found that iCal and the applescript sloooow down over time and it is best to quit both, maybe even restart and then start the process again. Guess I might never figure this one out.
Thanks for the help,
dan
