save different date format into mysql

I have a datetime mysql column. I send an insert command with an date format:

YYYYMMDDTHHiiss

The date value was correctly stored as date time format of mysql. Is this the correct way or would it be best practice to send my date in format?:

YYYY-MM-DD HH:ii:ss

Thanks !
