The values of all system fields in this table are set implicitly when the program is started, every time a
screen of a
dynpro is sent, and when the
internal session 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. If sy-zonlo
is initial, sy-timlo and sy-datlo have the same values as sy-uzeit and sy-datum.
