The issue is SMC needs the thermal & voltage sensor inputs from the battery without them SMC goes into CPU Safe Mode which ramps up the fans and lowers the CPU’s clocking. So you do need a battery sorry 😢
As for the clock & date, without power the clock dies often just going to the default value or if there was still a bit of power in the logic board it might hold for a minute or two.

If we compare to a desktop which offers a button battery to hold the settings and power the clock the MacBook laptops leverage there main battery so without it you won’t have a means to power the clock when the AC power is disconnected.
