(1) Add LargeInt cast to date and datatime, see #3864
LargeInt can cast to date and datatime. Fix this error:

(2) Add local timezone info to stale_version_path_json_doc rest api
Add timezone to "last create time" field.
{
"path id": "1",
"last create time": "1970-01-01 10:46:40 +0800",
"path list": "1 -> [2-3] -> [4-5]"
},
and add timezone to the test unix, see #4121 .
