[Qt-creator] Bug at the compilation checked

[alpha_one_x86]

Hello I have found this bug:
I have do editing, after I have clicked build I have run the binary,
it's not the good, I remove it I re run build it, that's no regen the
binary, I see:

Running build steps for project ultrabenchmark...

Creating gdb macros library...

QMAKESPEC set to linux-g++ overrides mkspec of selected qt
/usr/share/qt4/mkspecs/linux-g++-64

Configuration unchanged, skipping QMake step.

Starting: /usr/bin/make -j5 release -w

make: Entering directory `/home/user/Desktop/ultrabenchmark'

make: Warning: File `release' has modification time 42 s in the future

make: Nothing to be done for `release'.

make: warning: Clock skew detected. Your build may be incomplete.

make: Leaving directory `/home/user/Desktop/ultrabenchmark'

Exited with code 0.
Creating gdb macros library... -> should only execute on debug mode not
in release mode?
When I close Qt creator and reopen it that's regen my binary, or if I
don't want close I need run make in console.
