Description: LibreOffice Calc does not apply HH:MM:SS time format value to value displayed in Input Line. If one or more cells are formatted with the Time format "HH:MM:SS" (24-hour clock), the value in the Input Line is displayed using the "HH:MM:SS AM/PM" (12-hour clock) format. Value in cell shows correctly UNLESS the Input Line is selected (in which case it shows the incorrect (12-hour) formatting). Steps to Reproduce: 1. Open LibreOffice Calc 2. Select a column OR select a cell 3. Right click 4. Select "Format Cells..." 5. Select Category: Time 6. Select Format HH:MM:SS 7. Select Language English - USA 8. Click OK 9. Click formatted cell 10. Enter "00:02:30" (for 00h 02m 30s) 11. Click off cell 12. Click back on cell and examine Input Line value Actual Results: 12:02:30 AM Expected Results: 00:02:30 Reproducible: Always User Profile Reset: No Additional Info: Can duplicate under 7.5.4.2 (X86_64)/Build 36ccccfd35 under Windows 10.0 Build 16299. Can duplicate under Build ID 6.4.7.2-5.fc32 under Linux 5.11.
This is not a bug. Presented is the locale's time edit format, which for en-US (and very few others) happens to be the AM/PM one.
