Precise time measurement increases entropy

The next time I'm late, I'm going to explain that I don't keep time precisely because I'm trying to save the universe.

I'm worried that a savvy companion will point out that there is also the option of being imprecisely early...

For decades, since the now-grown kids were having to catch the school bus, we have had "The Clock Of The Universe" located where you can't miss it.  It is purposely set to be 7 minutes fast.  Everybody knows that it is 7 minutes fast (and there are other clocks in the same room).  It keeps everybody on time.

You made me chuckle with that one.  I suppose anytime one increases power to to add performance the heat byproduct causes increased entropy.  Overclock a CPU, more entropy.  Use a turbocharger, more entropy.
