Time which is destroyed or earned is given by -

=1/2*a*dt

=1/2*(12×10^-6) *(20-0)

=1.2*10^-4

Thus for a given single day, the period that is the time period is T=24*60*60

=86400

Thus, total time it will gain or lose is

= 86400*1.2*10^-4

=10.368 seconds/day.

Total time gained or lost is 10.36seconds/day.

Best wishes. Thank you.
