Title: #886: sudo: get timezone information from previous value when constructing new usn
pbrezina commented:
"""
Default value is `"0"`, it comes from `sysdb_get_highest_usn()`. So if the usn
number is zero and there is no timezone information and at the same time it is
modifyTimestamp instead of entryUSN, we need to get the timezone information from previous
value.
