The values of all system fields in this table are implicitly set when the program is started, every time a screen layout of a screen is sent, and when the internal mode is set. The last column of the table shows which of the system fields can be updated explicitly using the statement GET TIME.

The content of sy-zonlo is the user time zone described under System Time Zone and User Time Zone. The local values of sy-datlo and sy-timlo that make reference to the user time zone are determined from the system time and the system date.
