Well, that's an usual pattern: search something using a lax regexp,
discard false positives with parser, and return a specific value:

  (let ((clockstart
         (org-with-wide-buffer
          (org-back-to-heading t)
          (let ((end (save-excursion (outline-next-heading)))
                (re (concat "^[ \t]*" org-clock-string)))
            (catch :found
              (while (re-search-forward re end t)
                (let ((element (org-element-at-point)))
                  (when (eq (org-element-type element) 'clock)
                    (throw :found
                           (org-timestamp--to-internal-time
                            (org-element-property :value element)))))))))))
    ...)

I should probably rename `org-timestamp--to-internal-time' to
`org-timestamp-to-internal-time' if it is useful out of org.el.
