MySQL FROM_UNIXTIME

The MySQL FROM_UNIXTIME() function enables you to return a date representation of a Unix timestamp. More specifically, it returns the Unix timestamp as a value in 'YYYY-MM-DD HH:MM:SS' or YYYYMMDDHHMMSS format, depending on whether the function is used in a string or numeric context If your session time zone is set to SYSTEM (the default), FROM_UNIXTIME() will call the OS function to convert the data using the system time zone. At least on Linux, the corresponding function ( localtime_r ) uses a global mutex inside glibc that can cause contention under high concurrent load FROM_UNIXTIME() maps that value back to only one of the original values. Here is an example, using values that are distinct in the MET time zone The MySQL method from_unixtime however does not support any conversion of values greater than 2147483647 due to it's integer type limitation: SELECT FROM_UNIXTIME(2147483647); //2038-01-19 04:14:07 SELECT FROM_UNIXTIME(2147483648); //null The MySQL server itself is 64bit, but ofc. FROM_UNIXTIME would need to accept a long as argument

However, FROM_UNIXTIME() does not return NULL when 2147483647.9999999 (notice 7 digits) is passed. The value in the column c3 gets rounded outside of the supported TIMESTAMP range. Summary: 1. Values in the range (1 <= X <= 2147483647.999999) correctly convert to a valid non-NULL value. 2. Values in the range (2147483647.9999995 <= X < 2147483648) erroneously convert to an invalid datetime. By default, MySQL FROM_UNIXTIME function returns in YYYY-MM-DD format or YYYYMMDD format.

This isn't a particularly human readable format but can be converted in MySQL to a datetime value using the FROM_UNIXTIME function. Dates and times as timestamps. Back when I first started using MySQL and PHP and created an ecommerce system that was used on a number of websites, I decided to store datetimes as a UNIX timestamp for whatever reason. This made it easy to use the PHP date. MySQL FROM_UNIXTIME und negative Timestamps Seit der MySQL-Version 4 liefert die Funktion FROM_UNIXTIME([UNIX-Timestamp) für negative UNIX-Timestamps NULL zurück. Das ist natürlich unschön, da manche Datums-Funktionen über MySQL wesentlich schneller und einfacher zu realisieren sind als bspw. mit PHP MySQL doesn't handle timezone as part of a datetime anywhere. Timezone is handled separately. Hence, we can't dump the timestamps' timezone/DST status on a row by row basis. The problem is that the internal seconds since epoch is converted to a datetime in the first place. Two different internal values translate to the same external datetime, so it's not a 1 to 1 function. Having lost. Correct, it is the session (connection) time zone that matters most directly, because, when set, it overrides the system zone. FROM_UNIXTIME() converts the integer epoch time and converts it to a datetime literal in the session time zone. Insert/update to a TIMESTAMP then converts that datetime literal from the session time one back to UTC, which is how timestamps are stored in MySQL Description: The conversion from unixtime to internal format and back to unixtime eats up that single magic hour which is doubled during the switch from summertime back to the normal time. I expect, that for every X the expression UNIX_TIMESTAMP(FROM_UNIXTIME(X)) == X is true. But for times within that magic hour, this is sadly not true
