if a line oriented protocol, and don't need anything more than second
accuracy, it's easy enough to write a perl script for this:

stty </dev/ttyS0 baud...parity...etc...

perl </det/ttyS0 -ne 'print int(time())." ".$_;'

microsecond and by-byte is let as an exercise to the reader (read: get
a timing library from CPAN and use sysread/syswrite)
