I'm having a problem with a CD-ROM vendor. When we mount their CD-ROM, the time stamps on the files appear to be in GMT, so our OS (SunOS 4.1.2) cheerfully adjusts the time stamp -0700. Well, the indexing software is something called ISYS 3.0 (by Osyssey Development of Denver). When it originally did the indexing of the files, it noted the time/date stamp. Now, when it locates the files, it compairs the current time/date to the stored one, and if it's changed, it warns you and then will not highlight your search terms in the file. Since some of these files are very long, not highlighting the search term can often make the query useless. I understand that this software was originally for files on a hard drive, so the warning makes sense. However, I think the fault lies in the original pressing of the disk: how did a GMT time stamp get put onto the disk? It's ISO-9660 format. Some more background, in case it's important: to get around this, we've copied the whole CD-ROM to a disk drive, updating the time stamps as we do. Works fine till we hit something like last Sunday; daylight savings time. Then we have to re-timestamp. We mount the CD-ROM on PC's using PC-NFS however, the change in the date is happening before the PC ever sees it. The outfit (CD-ROM Library Inc.) that makes the disk (Oregon Law CD-ROM; AKA ORLAW) is based about 45 miles from us, certianly in the same time zone. I guess my questions come down to this: has anyone seen anything like this before? and Does the ISO-9660 format have some accomodation for timezone information? The one person I've talked to from the company is being very hard nosed, telling me basically that it's a problem at our end. I'd like some ammunition to back up my claim that there's something wrong in the indexing. Thanks a lot. Respond to me directly and I'll post a summary if there's interest (though I will follow these groups for awhile to see any posted replies). - Mike Myers, Willamette University
