 * This file defines a timer interface similar to GTimer, but defined in real
 * wall-clock time. A GTimer may stop counting while the computer is suspended
 * or the process is stopped:

 * but a DrwTimer keeps counting regardless.
 *
 * Currently this only provides second resolution as compared to GTimer's
 * microsecond resolution, but a typing break program doesn't really need
 * microsecond resolution anyway.
