Strange behavior of P_max_year_batt when changed timezone

[diegopescoalcalde]

While I was testing different timezones in the script I realized that when I used US/Central timezone there was a significant change in the result of P_max_year_batt as you can see in the last two rows of the picture below. Those results were reproduced with the default input data, just by changing the timezone from US/Central to a different one. I tested with many other timezones and the only one that shows a different result is US/Central. I was not able to find the root cause for that. If you have any theories on what may be happening I would be happy to test.
