Time zones are often changed: of course, when it happens, it is desirable to update the time zone database as soon as possible.
Firebird stores WITH TIME ZONE
values translated to UTC time.Suppose a value is created with one time zone database, and a later update of that database changes the information in the range of our stored value.When that value is read, it will be returned as different to the value that was stored initially.
Firebird uses the IANA time zone database through the ICU library.The ICU library included in the Firebird kit (Windows), or installed in a POSIX operating system, can sometimes have an outdated time zone database.
An updated database can be found on this page on the FirebirdSQL GitHub.Filename le.zip
stands for little-endian and is the necessary file for most computer architectures (Intel/AMD compatible x86 or x64), while be.zip
stands for big-endian architectures and is necessary mostly for RISC computer architectures.The content of the zip file must be extracted in the /tzdata
sub-directory of the Firebird installation, overwriting existing *.res
files belonging to the database.
