Two clocks must be specified. All names must contain 4 or less characters. The second part of the file is the clock information. This has one entry per line. Each line has the clock name followed by the start time, the offset and the drift rate.
Positive offset means the master clock is ahead of true time.
Positive drift means the master clock is fast. This option tells the program to use pulse time set information to get clock drifts and corrections. If this option is selected, the output is not a valid PCF file and will not be intelligible to clockview or clockcor . Thus the user may input many sequential logfiles on the command line and recieve one PCF file for all of them. The resulting PCF file will consider messages across boundaries of logfiles.
