================
Comment at: flang/runtime/time-intrinsic.cpp:122
+  constexpr auto max_clock_t{std::numeric_limits<std::clock_t>::max()};
+  unsigned_count_t maxCount{GetHUGE(kind)};
+  return max_clock_t <= maxCount ? static_cast<count_t>(max_clock_t)

> Isn't maxCount actually GetHUGE - 1? (Since you're doing % at the end of GetSystemClockCount).
Thanks for noticing that!


================
Comment at: flang/runtime/time-intrinsic.cpp:153
+          ? unsignedNsecs
+          : unsignedNsecs / (NSECS_PER_SEC / MILLIS_PER_SEC)};
+  // Return the modulus of the unsigned integral count with HUGE(COUNT).

Sure, will do.


================
Comment at: flang/unittests/Runtime/Time.cpp:71
+  EXPECT_GE(start8, 0);
+  EXPECT_LT(start8, max8);

Good idea, will do.
