o Setting the time back - unsorted
In case of an unsorted profile all profile entries remain in the buffer, which will lead
to duplicated entries. Table 24 shows a profile before and after (Table 25) a time
change backwards from 21:16 to 20:42.

• Profile reset
If the reset method is executed explicitly or implicitly (as a consequence of a modify-
cation in the data structure of the profile, comp DLMS UA 1000-1 Ed. 12.0. the first
entry after the reset will contain a valid registration period (considering the modified
data structure, if the reset was the consequence of a modification).
Table 26 shows the first entry after a reset at 15:45:35.
