current year + 50] (or [entered_date; current_year + 50] if old date already entered) because:
The type_de_champ Datetime is used for close future dates and very close past dates (for accident declaration for ex.)
The select currently has a range from 1950 to 2100, so 70+ years not supposed to be used, leading to:
- many bad data entered (0000 or 1950 to not scroll)
- making it difficult for users to give the proper date (current date is lost in the middle of 149 others) so risk to be lazy and select a random one or genuinely make a mistake
