Fix crash in CollectLocalCpuUsage. It is possible for time to travel "backwards" (currentTimeMillis() returning a value smaller than an earlier call to the same method). If time traveled backwards by at least 2000 milliseconds then this code would try to create an array with a negative length, causing an exception. This change doesn't fix the underlying problem (the class performs a lot of unsafe time math) but bounds the array creation to not use negative values. RELNOTES: None PiperOrigin-RevId: 271572798
