Unfortunately, this is a know problem with gettimeofday() and such adjusting programs. For small clock shifts, rdate should use adjtime for getting a smooth shift. For bigger shifts, gettimeofday() indeed gets shifted. What may be instead on systems that support it is clock_gettime(CLOCK_MONOTONIC, &tp); which is asserted to be monotonic, but that won't be usable on all systems. I don't know any function that would just return the time starting from the boot of the computer. I'd say brltty should hence have "current" and "shift" variables, current storing the last gettimeofday, and when we notice that gettimeofday becomes less than current, increase shift. Then we can use (gettimeofday + shift) which is monotonic. Samuel _______________________________________________ This message was sent via the BRLTTY mailing list.
