[PATCH rt-tests] pi_stress: remove timestamp of compilation from version output

[PATCH rt-tests] pi_stress: remove timestamp of compilation from version output

[Uwe Kleine-König]

Having the date and time of compilation is hardly useful and is in the
way for reproducible building binaries.

Hello,

a few people work on getting reproducible builds for Debian. Using
__DATE__ and __TIME__ obviously makes the rt-tests package fail to
compile in a deterministic fashion.

Best regards
Uwe

We used faketime (fed from changelog) to achieve the same goal but we
still got the warning while beeing deterministic. As a plus the build
crashed on hurd :)
