file-access-time filenameprocedure
set! (file-access-time FILE) SECONDSsetter

Gets or sets the access time on FILENAME.

On most platforms modification and access time must be set together, so this usually incurs a separate call to get the current modification time. For efficiency, use change-file-times when you want to set both.
