sceKernelGetProcessTime and sceKernelGetProcessTimeCounter subtracted GetStartNanos() from GetMonotonicNanos() in one expression. GCC reads the clock first, so on the first call in a process the start was captured after it and the result wrapped to about 2^64. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
