=head2 Timestamps

For syncronization purposes, all records which have the "modified" flag set are
timestamped with the current time.  All records with have the "modified" flag
unset are timestamped with "0" (very, very old).

=head1 Deleted Records

PDB records which have the "deleted" flag set are removed as part of the initialization
process.  The "archive" flag is ignored. 

=head1 Categories

For convienience, a record's category is treated like any other attribute.  New
categories are created as necessary.  Moving a record to a new category will achieve
the expected result during synchronization.
However, because renaming a category does
not cause affected records to be marked as "modified", category renaming operations will
be lost during synchronization.
