mysql - Time information of type DATETIME alternative with BIGINT or DOUBLE (Unix Time) -


let's i'm stuck mysql 5.5 , i'm not able change 5.6 or 5.7, therefore i'm not able use datetime fractional seconds, information need. know best solution. 1 of alternatives i've been thinking use bigint save information form of bash command date +%s%n (unix time) or double if want separate seconds , fractions of seconds (i.e. date +%s.%n).

what drawbacks of such configuration? besides not using standard format.

you can use bigint store unix time in milliseconds (javascript timestamps).

or, either of other solutions (fractional-second time in double or unix time in bigint) work.

the important thing table of size ability index column.
