Example:

#check if date entered as intented, format it properly for MySQL
lastvisit = datetime.strptime(lastvisit, '%d %m %Y').strftime('%Y-%m-%d')

The above code gets the datetime string in a specific way and then 
convert it to another format. All happens in one line clear and simple.

Now, in the following statement there shopuld be some way to check for 
daylight saving time so i would aboiut add +2 in winter or +3 for greek 
summer time.

lastvisit = ( datetime.utcnow() + timedelta(hours=2) ).strftime( 
'%y-%m-%d %H:%M:%S' )		# MySQL datetime format

I think + timedelta(hours=2) should be substituted with something else 
but i don't with what.
