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.
Keep the refrigerator and freezer doors closed as much as possible. A refrigerator will keep food cold for about four hours if the door is kept closed. A full freezer will hold its temperature for about 48 hours (24 hours if half-full).
