Name:
isofs.st
Purpose:
Records a time point at least 1 second before any nodes were added to a
freshly loaded or created ISO image. Nodes in the image which have
younger timestamps are suspect to have changed their content during
image production and might bear inconsistent content.
The RRIP timestamps have a blind second during which a change after
node registration would not be recognizable for incremental backups
which are based in "isofs.di" rather than on content comparison.
This attribute shall eventually be attached to the root directory entry
and be global for the whole image.
Format of Value:
Shall hold UTC seconds since 1970 as decimal number string without
terminating 0-byte.
Example:
{ '1', '2', '3', '8', '7', '4', '2', '2', '9', '6' }
