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.
When in doubt, throw it out! â  If your power was out just a few hours and you didnât open the refrigerator or freezer, chances are the food is OK. A refrigerator should keep food cold for four hours and a half-full freezer 24 hours (48 hours if the freezer is full) if you donât open the doors. â  Try not to open the refrigerator and freezer doors (doing so lets the cold air escape). â  Surround food with ice to keep it cold or place in a cooler to keep it cold.
