Hello Bernardo,
You could have a look at:
http://lists.apple.com/archives/applescript-users/2007/Nov/msg00511.html
Other threads appeared later on the list as well, all with strange behaviors of dates in AppleScript on Leopard.
The bug seems to have been corrected somewhere between 10.5.3 and 10.5.8: your script appears to behave correctly here with 10.5.8.
If updating the OS isn't an option, but you may afford a slight speed decrease for convertUnixTimeStamp(), there's the quick and dirty workaround: proceed in chunks; for example:
on convertUnixTimeStamp(UTS) -- For 10.5.x, with UTS > 0
local D
set D to current date
set time of D to 0
set day of D to 1
set month of D to 1
set year of D to 1970
set UTS to UTS as number
repeat while UTS > 500000000
set D to D + 500000000
set UTS to UTS - 500000000
end repeat
set D to D + UTS
end convertUnixTimeStamp
HTH,
Axel
