Hello, For the clock table `untilnow' behavior, we set the starting point to a really old date, but that falls outside the YYYY-MM-DD that org-parse-time-string was designed to handle. I've reworked org-clock-special-range to use nil to represent the starting bound for `untilnow' and updated org-parse-time-string to mention the YYYY-MM-DD assumption.
Please let me know if you have any objections. Otherwise, I'll apply the following commits to maint in a few days. org-clock: Simplify `untilnow' range logic org-parse-time-string: Describe time stamp matching behavior lisp/org-clock.el | 9 ++++----- lisp/org-macs.el | 4 +++- 2 files changed, 7 insertions(+), 6 deletions(-) -- 2.20.0
