Time for a New Watch
In an environment with extreme temperature fluxuations, a scientist noticed his watch was 1/2 minute fast at nightfall, but at dawn, it had lost 1/3 minute, making it only 1/6 minute fast. On the morning of May 1, he accurately reset his watch.
On what date was the watch 5 minutes fast?

net gain per 24 hrs =1/6 min
after 27 days and nights will have gained 4 1/2 mins,
gains 1/2 minute by evening of 28th day
hence gains 5mins by 28th may
