Why isn't the "last access time" part of the filesystem library?
Looking at the filesystem library and the attributes work in boost- sandbox, I don't immediately see "last access time" being available for a file or directory. "Last access time" was included in Dietmar Kuehl's original dir_it. Can someone kindly tell me why this was removed? It's highly useful, and part of every filesystem that I've seen. Thanks, Rick

ISO/IEC 9660:1999 filesystems don't supply a "last access" time stamp, perhaps because the original uses were on write-once media. Perhaps we should do more to support attribute query within the main library, but I don't really think we should include any that aren't reliably supported by at least POSIX, Windows, and ISO-9660 systems. --Beman

Your point is well made. However, it does seem odd that a feature that is useful for >95% of all typical usage shouldn't be in the library. Other options: -For ISO 9660 filesystems, use the time created as the "last access" time stamp. -Throw a "FeatureNotSupportedException" or somesuch. Richard
