Time :- duration for others , mystery for some us .

well , i did not want to think deep about this term but this is a very interesting topic to be talked about . what is time ? duration , hours , seconds , numbers that tell us continuum etc etc etc . what made time ? my take on this is time is infinite . time was never made . maybe time had different functions in it that activated when time ( imagine it as a energy here not as numbers ) kept on moving on . example :- universe was not formed in a snap an energy created it . this energy must be flowing already which activated another function thus leading it to create the universe . but anything infinite has a starting point too . so does time have a starting point ? if it does then what could it be ? if it does not then what created this energy that is known to be time ? . ( need valid arguments and responses )
