setInterval working differently for a function with Global Variable & Local Variable!

While trying to see whether Time changes if variable is outside the function and, Found that the function with local variable doesn’t change Time ! So can anyone explain me why does this happen? https://code.sololearn.com/WEm06Nrl88q0/?ref=app

You get time from a var "d"... Now in "printtime" function you init (local) "d" any time that this function its called hence it will contain always up-to-date time... In "printer" function you dont init "d" (the global one that you have inited on line 15) but use it for get hour, minites and seconds and because your global "d" its setted only one time (on line 15) it will contain always same date hence in "printer" function you will retrieve always same hour, minutes and seconds.... Sorry i cant explain better

Your forget that on local one, you init all vars (hour, minute etc) to current time (because your get it at begin of function)... With global one you init d one time only before call it hence you will get same vars (eg. will be printed same time)
