Package tzdata provides an embedded copy of the timezone database. If this package is imported anywhere in the program, then if the time package cannot find tzdata files on the system, it will use this embedded information.
Importing this package will increase the size of a program by about 800 KB.
This package should normally be imported by a program's main package, not by a library. Libraries normally shouldn't decide whether to include the timezone database in a program.
This package will be automatically imported if you build with -tags timetzdata.
