Hello Uwe,
generally a reasonable idea. But your patch breaks the number of items
a shell script might expect to read when parsing a line.
What about
printf("(%03ld.%06ld) ", diff.tv_sec, diff.tv_usec);
as i would not assume timestamp diff > 999 secs are relevant ?!?
And if you have an offset greater than 999 secs you probably want a
ragged output to detect the heavy offset ;-)
Regards,
Oliver
