Always walltime
Locked
 
|
We use the -walltime command switch. It means having to define and maintain a Windows shortcut just to use it. Anybody know of a way to make walltime the default behavior so we can get rid of the Windows shortcut?
Windows platforms On MS Windows systems, this switch is supported: -walltime Use the lower-resolution GetSystemTimeAsFileTime instead of QueryPerformanceCounter to drive the microsecond clock. This is useful for long-running applications that are very time sensitive, since the default QueryPerformanceCounter, while higher-resolution, tends to drift from the wall clock over a period of hours.

Which version are you using?
Since at least 7.4d this switch does not do anything. The current explaination when you call visual -? is "-walltime ignored option retained for backwards-compatibility". I think there was a change to the VM so that the switch is not needed anymore. Ralf Paul Baumann wrote: > We use the -walltime command switch.

Ralf,
Good catch. We are using a version that has it disabled. Goodbye shortcut--at least some of them. Reinout, I'll look into reshacker. Thanks. I was looking at a bat-to-exe program yesterday but several people had commented that some virus checkers mistake it as dangerous.
