tsci2d - user mode daemon to keep precise PC clock by ultilizing TSC
register.
tsci2d [-h]
The traditional Unix gettimeofday()
system call returns system time. Due to the limitation of clock interrupt
update, the time reported only provides a coarse interpolation at microsecond
level. TSCI2 (TSC-Internet2) package is used to provide precise time scaleing
at microsecond level.
This daemon keeps itself synchronized with the system
clock, at the same time maintain a conversion table for precise interpolation.
Conversion table is in the form of named shared memory and is accessible
by the tsci2 library.
Only one copy of tsci2d is allowed to run in the
system at a time. All daemon messages are logged to syslog.

tsci2d returns a zero exit status if it quits normally. Non-zero
is returned in case of start-up failure.
