I don't even know if this is an install shield issue i suspect not but I wondered if anyone had seen it.
Some files when installed have a different modified time by one hour.
e.g. if you look at the file properties before the file is installed the last modified time might be 11:02. After installing the same file will show the time as 12:02.
It doesn't happen for all files and the difference always seems to be exactly 1 hour.
I suspected something to do with different time zones or British Summer time (Daylight Savings time) but cant quite figure out why or what changes the time after installing.
Has anyone seen this before?
