You can use the following regex to select only the date and by substituting it with your desired date you can get the expected result :

\d{4}-\d{2}-\d{2}

python

import re
regex = r"\d{4}-\d{2}-\d{2}"
date = "2017-02-03 14:07:03.840"
subst = "2015-01-01"
result = re.sub(regex, subst, date, 0)
if result:
    print (result)
