4) and updateLog/updateAlarmLog
+ checking for non-overriting (master/slave)
+ if _DB_flag write info to DB
+ if _printer_flag write info to printer
+ if _time_flag and midnight change AlarmLog and OpMod extension
Parameters: 1) filePointer
2) Buffer
3) TimePointer (If we use (very often) current time = NULL )
4) Special flag for distinguish usual format of alarm (type =REGULAR_RECORD=0)
and unusual (type = {CONNECT_ALARM,STOP_LOGGING_ALARM...}
