cannot enter event time that starts after 12 pm

When I create a new event on my calendar if I try to enter a time after 12:00pm (midday) Lightning immediately changes it to the am equivalent. For example, if I enter a time of 14:00 it changes it to 02:00, 16:00 gets changed to 04:00 and so on. It does not matter if I select the time with the mouse from the drop-down or enter it manually from the keyboard. Toggling the "Keep the duration when changing the end date" option makes no difference. Pre-12:00pm times work fine as do all day events.

I am using version 6.2.6.1 of Lightning and the 32-bit 60.6.1 version of Thunderbird.

Any help would be much appreciated. Thanks.

Thanks for your help but I'm afraid I became so frustrated that I just uninstalled and reinstalled everything. And guess what - it's working fine now. I have no idea why it happened but I guess something must have been corrupted somewhere.

Anyway, thank you so much for your interest it was much appreciated.

What 'language' version of Thunderbird are you using? What OS are you using?

Are you using the correct timezone? Windows: Menu icon > Options > Calendar > 'General' tab

Mac: Thunderbird > Preferences > Calendar > 'General' tab

Linux: Edit > Preferences > Calendar > 'General' tab

Thanks for you reply.

Sorry I omitted my OS, I'm running Windows 7 64-bit Ultimate. I am using the UK English version of Thunderbird.

I've attached images of my calendar and general options as requested. I have tried both application and regional settings in the date and time format but neither work.

Thanks.
