\subsection{Detailed Description}
Public defs for Time Hack Services. 

\begin{Desc}
\item[Author:]Ed Bacho -- \href{mailto:ebacho@slac.stanford.edu}{\tt ebacho@slac.stanford.edu}\end{Desc}
This module handles calculation of absolute time using the \char`\"{}time hack\char`\"{}. The absolute (or true) time is provided once a second through a combination of a 1PPS (1 pulse per sec) hardware pulse and a time tone message (\char`\"{}at the tone the time will be\char`\"{}) that preceeds it. The time provided in the time tone message from the scapecraft is in micro\-Sec since 1/1/2001.

This file has routines for adjusting the time on the CPU clock by using the WCT\_\-set/get routines, therefore one can only get the current time thru WCT\_\-get(). THese are based on a sub-multiple of the CPU's 33 MHz PCI clock.

The determination of the absolute time from event and LCB times is handled in other time hack files.

This module only truely works on the Rad750 which has the PPS input thru the PID registers. The mv2304 version starts up a task to simulate the PPS but it should therefore show no drift (since its locked with the clock)

Inputs:\begin{itemize}
\item time tone message every sec (500-800 m\-Sec before pulse) giving next abs\-Time\item HW 1PPS pulse every sec from GASU (although originates from spacecraft)\end{itemize}


Output:\begin{itemize}
\item can obtain corrected absolute time thru WCT\_\-get()\end{itemize}

The only routine in THS/DDT that actually does any work. The first time this routine sees a timetone message, it will attempt to set wall-clock time (none too accurately, probably good to about 1/10 second), and call WUT\_\-sys\_\-adjust() to get all extant timeouts adjusted. After that, wall clock time simply free- wheels based on the CPU clock (which DDT will likely adjust).\hypertarget{THS_8h_a16}{
