don't forget to write Berlin time or Beijing time, so people won't be confused about time zones, since some experts write them in some odd UTC/GMT format with + sign which is complete mess especially with summer/winter time in Europe, while all year same time in China I always write my Chinese colleagues time either in Chinese/Beijing time or Berlin time to clarify what time zone we are talking about, because it's not so obvious since some of them work until midnight or even 1AM local Chinese time
