* 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:
|
||
|

*
|

|
|
* 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.
