For the impact after changing system time zone:

Please be aware that changes in time zone settings always requires a system restart. The R/3 system time zone is only used in very rare cases.
Nevertheless I would strongly recommend not to start any jobs or time critical processes during this time period.
When you change the time zone settings on R/3 system the time saved on database will not be recalculated. Nevertheless some documents might
display another time because the calculation then starts with the creation time on database and the 'new' system time e.g.'CET'. But this should not
cause any inconsistencies. But as mentioned we would recommend to avoid the creation of documents in the time period.
