Using LibreOffice Calc v25.8.4.2 on Windows 10 Pro
From main menu, Tools, Options, Languages and Locales, General, Formats, Date acceptance patterns: I’ve been unsuccessful to add this and similar patterns like
YYYY/MM/DD HH:MM:SS
This question comes as I have been trying to paste copied values like 2018/11/30 15:36:30 into one cell and 2018/11/30 11:45:00 into another to produce in a third cell, their difference; e.g., 03:51:30
Thank you for any help.
