>From a0792b3900812b6a2385794f30ba7c057bc9fcf7 Mon Sep 17 00:00:00 2001 From: Jack Henahan Date: Sun, 21 Jan 2018 10:40:22 -0500 Subject: [PATCH] org-clock.el: Improve `untilnow' range behavior and performance * org-clock.el: (org-clock-special-range): Set `untilnow' to use the year -50000, rather than the earliest representable date. (org-clock--oldest-date): Remove. The `untilnow' range relied on the constant `org-clock--oldest-date` to find the earliest representable date, which caused delays when loading `org-clock' on systems where `most-negative-fixnum' is large. This change removes that constant in favor of a simpler hack to produce a range between the current time and before the dawn of human civilization. If this breaks your workflow, please report to the Time Police. --- lisp/org-clock.el | 35 ++--------------------------------- 1 file changed, 2 insertions(+), 33 deletions(-) diff --git a/lisp/org-clock.el b/lisp/org-clock.el index 496c4310a..d580ffa43 100644 --- a/lisp/org-clock.el +++ b/lisp/org-clock.el @@ -468,38 +468,6 @@ to add an effort property.")
