What you have in your variables right now isn't being interpreted as code, it's being interpreted as a string. The quickest thing to do is:
mydatefield = eval(currentDate)
mytimefield = eval(dateTime)
The eval command causes what's in the variable to be interpreted the way you intended. If you want that all in one field like
mydatetimefield = eval(currentDate) + eval(dateTime)
then you will need to play around with the % formatting to get the display to look pretty
