Split org-mode CLOCK entry while preserving time.
Clocked some time in but want to split it up into multiple entries? Worry no more! Place the cursor on a CLOCK entry and run org-clock-split. Type in a offset to split the record at, such as "15m1h", and voilà! The entry will be replaced with TWO clock entries, preserving the total amount of time of the original entry.
Usage Example
If cursor is on
CLOCK: [2018-08-30 Thu 12:19]--[2018-08-30 Thu 16:05] => 3:46
Running
(org-clock-split "1h2m")
Will produce
CLOCK: [2018-08-30 Thu 12:19]--[2018-08-30 Thu 13:21] => 1:02
CLOCK: [2018-08-30 Thu 13:21]--[2018-08-30 Thu 16:05] => 2:44
