There is no need to add to the API. You already have Smalltalk seconds
at any level of precision care to use.

  now := DateAndTime now. "==> 2020-05-01T09:54:37.73365-04:00"
  seconds := now asExactSeconds.
  seconds asScaledDecimal. "==> 3765794077.73365s5"
  copyOfNow := DateAndTime fromSeconds: seconds.
  copyOfNow utcMicroseconds. "1588341277733650"
  now utcMicroseconds. "==> 1588341277733650"
  copyOfNow = now. "==> true"

Therefore, to avoid astonishment when using it with the "utc" API of DateAndTime, rename it without the "utc" prefix.

However, it is probably not a good idea to modify the existing method.
It may be safer to "deprecate" it by hiding it in a private category,
and updating the method comment to encourage people to use the new
name in the future.
