We always read system uptime before log start time. So the uptime
should be always smaller number, except it includes system suspend
time. It seems better to ask for --rel and exit() than try to be
smart and try to recovery from this situation or generate huge
messy graphs.
+ if (graph_start < 0.0) {
+ fprintf(stderr,
+ "Failed to setup graph start time.\n\nThe system uptime "
+ "probably includes time that the system was suspended. "
+ "Use --rel to bypass this issue.\n");
+ exit (EXIT_FAILURE);
