Thanks for your help.I have finished this problem.This issue isn't about my PC System time or date.Because my ISP--China Mobile cut off export flow that network of local area connected some overseas services recently,inculde of some steam servers.At present, I do not know the reason for this action.I solved this problem with network acceleration or proxy software.Thanks you and your team for their help again.
