"at_time" with a time string as described with command -alter_date chooses
the last session or track where the modification timestamp matches the given
time within the same second.
@*
"before" with a time string chooses the last session or track of which
the timestamp is older than the given time. But it does not match an entity
with exactly the given time.
@*
"not_after" is like "before" but also matches an entity with exactly the
given time.
@*
"after" with a time string chooses the first session or track of which
the timestamp is younger than the given time. But it does not match an entity
with exactly the given time.
@*
"not_before" is like "after" but also matches an entity with exactly the
given time.
@*
Comparison of time entities is done with an accuracy of one second. I.e. the
centiseconds of ISO 9660 timestamps are ignored.
If -toc_info_type is set to "creation_time", then the comparison is done
against the creation timestamp of track or session rather than the modification
timestamp. The output of -pvd_info shows both timestamps as "Creation Time:"
and "Modif. Time :".
@*
The time comparisons pick first and last matching sessions. If the sequence of
timestamps on a drive is not chronologically ascending, the picks might not be
the best choice.
In this case look at the output of -toc_info_type "mtime" -toc and choose the
desired entity by "session", "track", or "sbsector".
@*
Addressing a non-existing entity or one which does not represent an ISO
image will either abandon -indev or at least lead to a blank image.
