More info: This appears to be failing in org-parse-time-string, when it compares the string "" to org-ts-regexp0 Nothing in the regexp nor in the call tree is attempting to process the special time values. It seems like there is missing code needed either in org-parse-time-string to handle the special strings, or in the clock-updater code to convert the special time strings to actual times before passing them on. Is there somewhere else I should be submitting this bug?
