TIMESET  7.21
                                June 13, 1992

TimeSet 7.21 is a maintenance version correcting a flaw in Version 7.20
that prevented it from detecting nonstandard serial port configurations
such as an unusual port address or IRQ number.  This made it impossible
for anyone not using a standard address or IRQ to detect connection with 
one of the atomic time sources.  The flaw caused no problem for users whose 
computers have standard serial port configurations.  There is good reason, 
however, for all users of version 7.20 to replace it with 7.21, namely that 
the precision and accuracy of time readings and settings have once again 
been improved significantly.  With Tom Becker's RighTime 2.54 installed, 
trained for optimal clock drift correction and providing .01-sec resolution 
to the DOS clock, line delay calls made in quick succession to time services
providing line delay measurement -- the NIST (Boulder), USNO (Washington), 
Tom's TimeGen service (Dallas), and two European services (Sweden and 
Austria) -- consistently agree within .01 second and very often agree 
exactly.
