Break from while loops after specific time

Do you set the clock in your house to twelve o'clock when you boil an egg No, you don't. You look at the clock, note down the time and check the clock regularly to see if the desired time has elapsed.

very compact description of the basic principle

I have a long code with multiple while statements for serial / i2c read

If the i2c-device does not answer the i2c-routine will hang. i2c-communication is blocking. If this device is a professional build device or a professional build i2c-chip its i2c-bus will work very reliable. If it is something hand-coded for communication between two microcontrollers I would change this communication to serial, because serial can be configured with timeouts.
