I'll just use a DS1307 or a DS3231... So it keep track of the time every day for me... instead of typing a new number/time in every time i start the arduino
Either use a hardware RTC like the DS3231 that you mentioned, or if you have WiFi or some other connectivity, grab the time from a network resource.
