Attività
Drift residuo <= 2sec
La propagazione dell'ora dal SAC ai Meter deve avvenire con un errore massimo di 2 sec
UNI/TS 11291-6 §7.5.2
Sotto i 60 secondi il Gdm può non effettuare la sincronizzazione
e/o può non generare l'evento di sincronizzazione
UNI/TS 11291-6 §7.5.2
Fra 60 sec e 4 ore [estremi inclusi], sincronizzazione con evento [o registri]
UNI/TS 11291-6 §7.5.2
Sopra le 4 ore, invalidare le letture
UNI/TS 11291-6 §7.5.3
Registrazioni a seguito di sincronizzazioni (non riaprire un periodo già chiuso)
UNI/TS 11291-10 §10.8.2 Il DC/GW può sincronizzare il GdM.
UNI/TS 11291-1 §4.3.1
Il GdM deve rifiutare i comandi di sincronizzazione dal DC/GW se la deriva in valore assoluto è
maggiore o uguale a 60 secondi. In tal caso una condizione di errore deve essere fatto pervenire
al SAC
Si possono accettare comandi per uno scostamento totale di 60 secondi al mese
Si assume [-11-4] che il timestamp contenuto nelle CF push sia sincronizzato con l'orologio interno
del GdM a meno di un tempo LBT (<= 0.8sec)
Conseguentemente tale timestamp è usato dal SAC come riferimento del clock del GdM e
confrontato con il relativo timestamp allegato alla APDU da parte del GW/DC

Activity
Residual Drift <= 2sec
Propagation of clock from HES to the Meters shall happen with a maximum deviation of 2 seconds
UNI/TS 11291-6 §7.5.2
Below 60 seconds, the Meter may not execute the synchronization
and/or may not generate the relevant synchronization event
Between 60 sec and 4 hours [extreme values included], the synchronization shall be executed
and synchronization registers shall be updated. It is optional to generate synchronization events
UNI/TS 11291-6 §7.5.2
UNI/TS 11291-6 §7.5.2
Above 4 hours, the readings (archive) shall be invalidated from the reception of the command
onwards.
Invalidation shall be active until a new valid clock setting / synchro command is received
UNI/TS 11291-6 §7.5.3
Intervals that are already closed cannot be opened (daily & billing)
UNI/TS 11291-10 §10.8.2 DC/GW can synchronize the meter
UNI/TS 11291-1 §4.3.1
The meter shall accept synchronization commands if the drift (in absolute value) is less than 60
seconds.
The meter can accept commands up to a total drift of 60 seconds / month
If meter is not synchronized in this way, the HES shall be informed
Due to UNI/TS 11291-11-4, it is assumed that the timestamp that is found in a PUSH CF is
synchronized with the internal RTC of the meter, with the precision of a LBT timeout [approx 0.8
secs]
This timestamp is subsequently used by the HES as a reference for Meter clock and it is matched
against the timestamp attached to that same APDU (PUSH CF) by DC/GW
