A multi-threaded, POSIX compliant, high precision interval timer for your terminal
gcc main.c -lpthread
tcc main.c -lpthread
interval-timer [flags] [interval length] [interval count]
| Interval length (Seconds) | Interval count | Time (MM:SS.sss) | Ideal Time (MM:SS.sss) | Drift (MM:SS.sss) | Error (%) |
|---|---|---|---|---|---|
| 05 | 02 | 00:10.003 | 00:10.000 | 00:00.003 | 0.03% |
| 60 | 30 | 30:00.210 | 30:00.000 | 00:00.210 | 0.007% |
The longer you run the program, the more accurate it becomes, curiously. Using threads also reduced my time drift over 30 minutes from 15 seconds to 0.21 seconds, a 98.6% decrease.
