The value is stored in the format "<minutes>:<seconds>".

The precision level of the value in the database is 1 second, but since different sources and techniques to obtain the value are used, deviations up to 3 seconds are considered to be within the precision of the database.

Sources

The data is obtained from different sources, among them are:

Gap position

It has been reported to tango.info: 

Prefix on CD. Suffix when ripped to 
individual track files - except last file.

XMCD

According to http://ftp.freedb.org/pub/freedb/latest/DBFORMAT 

The comments should also contain the string "# Track frame offsets:" 
followed by the list of track offsets (the # of frames from the 
beginning of the CD) obtained from the table of contents on the CD itself

valid XMCD files contain frame offsets from the beginning of a CD.

The standard does not define whether that is INDEX 00 or INDEX 01 as given in the cue sheets.
