What is going on with the date in the F-16 time page?

[FoxTwo]

Was on a server that uses the current date/time for a mission and it read MM/DD/YY 7/45/20

 

I created my own mission set to 8/8/2020 and this is what it displayed

 

Then I hopped on growlingsidewinder's server and it showed

 

41st day of December?

 

This a bug? Seems like a bug.
