These functions claimed to return error (an interface) and be implemented entirely in assembly, but it's not possible to create an interface from assembly (at least not easily). In reality the functions were written to return an errno uintptr despite the Go prototype saying error. When the errno was 0, they coincidentally filled out a nil error by writing the 0 to the type word of the interface. If the errno was ever non-zero, the functions would create a non-nil error that would crash when trying to call err.Error(). Luckily these functions (Seek, Time, Gettimeofday) pretty much never fail, so it was all kind of working. Found by go vet.

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.
After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.
Unless otherwise noted, the Go source files are distributed

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
