All Messages shows date in April
Dear Community,
I have installed Thunderbird on a new system and imported my mailbox and archives from my old Mac (both running macOS). I am currently using macOS Monterey 12.7.6 and Thunderbird 40.5.0 ESR (64-bit).
All messages—whether imported or newly received—both in the Inbox and in archives are showing the month as April (i.e., xx/4/xx). This issue also appears in the email body when replying or forwarding messages. Please note that the day and year are correct, only the month appears incorrectly as “4” (April)on all messages.
Messages in the imported local folder archives display the correct dates. I have email folders going back to 2006, and I would greatly appreciate your guidance to resolve this issue.
Many thanks in advance, Leonardo
