This package mainly exists to workaround an issue in Go where the serializer doesn't omit an empty value for time: https://github.com/golang/go/issues/11939. This replaces all release and hook object time references with the new time package so things actually marshal correctly Signed-off-by: Taylor Thomas <taylor.thomas@microsoft.com>pull/6679/head
