StoreTimestamp([I<keywords> OFFSET, TAIL])

=s measurement, analysis

store packet timestamps in packet data

=d

StoreTimestamp stores each packet's timestamp annotation somewhere in its
data.  Supply exactly one of the OFFSET and TAIL keywords.

Keyword arguments are:

=over 8

=item OFFSET

Integer.  Store the timestamp starting OFFSET bytes into the packet.  The
packet will be extended, if necessary, so that it's at least OFFSET+8 bytes
long.

=item TAIL

Boolean.  If true, the timestamp will be tacked on to the end of the packet.
