An issue with the date-time format of an e-mail

more options

I am using Thunderbird 54.0b2 (32 bit) portable (20170524131922)

After the last update the date-time format of the e-mails has changed to MM/dd/yyyy as seen in the upper part of the image. The date-time format of the OS is set in dd/MM/yyyy (as seen in the lower part of the image).

I need an advice how to change the date-time format of Thunderbird to the one set in the OS.

Thank you in advance!

Thunderbird uses the date format of your computer. Since you are using beta software and the portable version you should check with the people at portable apps.com. They support their software. https://portableapps.com
