Whether all of the given strings are valid units of time.

bool validTimeUnits (
  scope string[] units...
) pure nothrow @nogc @safe;

"nsecs" is not considered a valid unit of time. Nothing in std.datetime can handle precision greater than hnsecs, and the few functions in core.time which deal with "nsecs" deal with it explicitly.


assert(validTimeUnits("msecs", "seconds", "minutes"));
assert(validTimeUnits("days", "weeks", "months"));
assert(!validTimeUnits("ms", "seconds", "minutes"));
