Description

The program is given a date, a time, and a time zone and converts this information into a time stamp. The program can also include summer time in its calculations. The resulting time stamp is then converted to the local date and local time of another time zone. The following table shows several possible combinations of input and output, where spc stands for a space and - for no input or output.

The third and fifth rows demonstrate that invalid summer time data produces the value 12 in sy-subrc.
