Functions
constexpr auto	count_ms () const noexcept -> u64
constexpr auto	count_ns () const noexcept -> u64
constexpr auto	count_s () const noexcept -> u64
constexpr auto	count_us () const noexcept -> u64
constexpr	duration (u64 ns) noexcept
static constexpr auto	from_microseconds (u64 us) noexcept -> duration
static constexpr auto	from_milliseconds (u64 ms) noexcept -> duration
static constexpr auto	from_seconds (u64 s) noexcept -> duration
static constexpr auto	from_tod (u64 tod_units) noexcept -> duration
	Convert s390x TOD clock units to a duration. Calculation: NS = (TOD * 1000) / 4096 = (TOD * 125) / 512.
auto	zxfoundation::sys::time::initialize (const u64 tod_boot) noexcept -> void
	Initialize the global time system.
constexpr	instant (u64 ns) noexcept
auto	zxfoundation::sys::time::monotonic_now () noexcept -> instant
	Retrieve the current monotonic time (time since boot).
constexpr auto	nanoseconds_since_epoch () const noexcept -> u64
constexpr auto	operator+ (duration o) const noexcept -> duration
constexpr auto	operator+ (duration d) const noexcept -> instant
constexpr auto	operator- (duration o) const noexcept -> duration
constexpr auto	operator- (duration d) const noexcept -> instant
constexpr auto	operator- (instant o) const noexcept -> duration
constexpr auto	operator<=> (const duration &) const noexcept=default
constexpr auto	operator<=> (const instant &) const noexcept=default
auto	zxfoundation::sys::time::realtime_now () noexcept -> instant
	Retrieve the current realtime (wall-clock) time.
auto	zxfoundation::sys::time::set_realtime (const instant now) noexcept -> std::expected< void, lib::kernel_error >
	Adjust the realtime clock (e.g., NTP steering).
auto	zxfoundation::sys::time::tick_advance_wall (u64 tick_ns) noexcept -> void
	Advance the wall-clock offset by one tick's worth of time.
auto	zxfoundation::sys::time::tick_count () noexcept -> u64
	Return the current monotonic tick counter.
