New Thunderbird (version 60+) to show emails' date with four-digit again?

  • 772

Recently in Ubuntu 18.04 LTS we got a new Thunderbird version, jumping from version 52 something to now version 60.2.1

In the e-mail section which lists all e-mails, as well as in the individual e-mail's header, the date is now two-digit only compared to four-digit in the previous Thunderbird versions.

Can we somehow get four-digit dates again?

"about:config" doesn't seem to list a variable concerning such "date" settings. Also my Ubuntu is set to four-digit dates.

    Since Thunderbird version 91, you can customise the date formats using the config editor. Full instructions at the end of https://support.mozilla.org/en-US/kb/customize-date-time-formats-thunderbird

    Summary:

    • edit -> preferences, scroll to the bottom and click the button that says "Config Editor..."
    • create a new preference called intl.date_time.pattern_override.date_short with type string
    • set the value to dd-MM-yyyy (or MM-dd-yyyy or yyyy-MM-dd if you prefer a different order)
