This test sometimes triggers failures during build testing. For instance, see: https://lab.llvm.org/buildbot/#/builders/52/builds/10161, details: https://lab.llvm.org/buildbot/#/builders/52/builds/10161/steps/5/logs/FAIL__Clang__check-time-trace-sections_cpp . AFAICT the time between driver calling and checking its time tracker output is not guaranteed to be stable and small: ``` > head -2 check-time-trace-sections.cpp // RUN: %clangxx -S -ftime-trace -ftime-trace-granularity=0 -o %T/check-time-trace-sections %s // RUN: cat %T/check-time-trace-sections.json | %python %S/check-time-trace-sections.py > clang -S -ftime-trace -ftime-trace-granularity=0 -o /tmp/check check-time-trace-sections.cpp > cat /tmp/check.json | python check-time-trace-sections.py > sleep 10 > cat /tmp/check.json | python check-time-trace-sections.py 'beginningOfTime' should represent the absolute time when the process has started > ``` The attribute `beginningOfTime` was introduced here: https://reviews.llvm.org/D78030 One can change "10 sec" value to something longer, but I believe it's enough just to check that `beginningOfTime` exists and is not later than current time.
