the original request in LU-12026 was to update *time as a part of LSOM update, i.e. to be stored in LSOM ea, but implemented as a regular time update on close, what is obviously wrong because it breaks set-in-past functionality (and in general due to the reasons we have LSOM but not SOM) - close always sends *time but does not bother accurately re-gather them from servers, while the local cache could be already stale. in other words this will not work:
1. client1 open
2. client2 set-in-past
3. client1 close
the reproducer is attached:
— set-in-past on opened file
