[PATCH v1] perf: cast (struct timeval).tv_sec when printing

From: Pierre . Gondois
Date: Wed Feb 24 2021 - 13:25:39 EST


From: Pierre Gondois <Pierre.Gondois@xxxxxxx>

The musl-libc [1] defines (struct timeval).tv_sec as a
'long long' for arm and other architectures. The default
build having a '-Wformat' flag, not casting the field
when printing prevents from building perf.

This patch casts the (struct timeval).tv_sec fields to the
expected format.
