Daylight Saving Time in Mexico. In most of Mexico daylight saving time begins at 2:00 a.m. local time on the first Sunday in April. On the last Sunday in October areas on daylight saving time fall back to Standard Time at 2:00 a.m. local time. Central Standard Time (CST) becomes Central Daylight Time (CDT), and so forth.
It takes at least 2 - 3 hours to get completely cold if it's empty, up to 24 hours if it has food in it.But the food will still be kept cold enough during the original cooling process.ule of thumb is generally 48 hours in the refrigerator. It does not take more than 8 hours to properly marinate, but anything over 48 hours is too long.
Do not open the refrigerator or freezer door unless absolutely necessary in order to maintain the cold temperature. A full freezer will keep food frozen for about 48 hours. A freezer that is half full will keep food frozen for about 24 hours. An unopened refrigerator will keep food cold for about 4 hours. If available, add ice to the refrigerator to keep the food at a safe temperature if the power will be out for long periods of time. Do not place frozen food outside, even in winter.
