This struct provides a namespace for platform-neutral system-clock procedures.
Declared in <bsls_timeutil.h>
struct TimeUtil;This struct provides a namespace for a set of platform-neutral pure procedures to access real-time system clock functionality. High-resolution time functions intended for interval-timing return an interval in nanoseconds (1 nsec = 1E-9 sec) as a platform-independent 64-bit integer.
For maximum performance on some platforms where fetching the native clock is significantly faster than converting the fetched value to nanoseconds, this class also provides a "raw" method returning an opaque native time value and a conversion method returning a value in nanoseconds.
