Is there a way to insert an implied year into a month-day-time input value?

[Roger L Costello]

My input contains a month-day-hour-minute-timezone, e.g.,

.../09190935Z/...

I believe that the current year (2023) is implied. Is there a way to add the 
current year so that the result of parsing is the standard datetime format?  
E.g.,

<TimeOfReturnToOperations>2023-09-19T09:35:00+00:00</TimeOfReturnToOperations>
