// Package monotonicclock represents the imported interface "wasi:clocks/monotonic-clock@0.2.0".
//
// WASI Monotonic Clock is a clock API intended to let users measure elapsed
// time.
//
// It is intended to be portable at least between Unix-family platforms and
// Windows.
//
// A monotonic clock is a clock which has an unspecified initial value, and
// successive reads of the clock will produce non-decreasing values.
//
// It is intended for measuring elapsed time.
