Please describe the problem:
When I use it in Chinese locale below. I edit the register , the date field is wrong, there will be  a very large year like this "1250731年11月30日". This bug still exist at version 2.1.1.
$ locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT="zh_CN.UTF-8"
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=zh_CN.UTF-8


Steps to reproduce:
1. set the locale to zh_CN.UTF-8
2. enter the record in register
3. edit the date
