Time related object on ESME


Italicised terms in this Section shall have their Blue Book meaning.

An ESME shall have a Data object with OBIS code 0-0:94.44.100.255 where attribute 2 of that object:



  • shall be a double-long-unsigned value;

  • shall have a value set by the ESME to the number of seconds between 0 hours 0 minutes 0 seconds on 1st January 2000 UTC and the value of UTC time specified by attribute 2 of the Clock object with OBIS code 0-0:1.0.0.255;

  • shall be the value recorded by the ESME in attribute 2 of any Profile generic object entry as the date-time stamp, at the time the entry is added;

  • shall be the format recorded by the ESME in attribute 2 of any Profile generic object entry in other date-time fields.

Correspondingly:

  • the ‘from_value’ and ‘to_value’ fields in the selective access structure, which are required by the GBCS when accessing attribute 2 of any Profile generic object directly, shall be double-long-unsigned attributes containing a date-time specified in seconds since 0 hours 0 minutes 0 seconds on 1st January 2000 UTC; and

  • the restricting_object field in the selective access structure shall be set with values of class_id = 1; logical_name = 0-0:94.44.100.255; attribute_index = 2 and data_index = 0.

The Blue Book requires that, for a Data Protection class object, restriction_by_date access has from_date and to_date specified as octet-string. Thus, where a Use Case requires that the contents of attribute 2 of a Profile generic object are returned in Encrypted form (and so accessed via a Data Protection object):

  • the from_date and to_date fields in the Command shall be octet-strings formatted as per section 4.1.6.1 of the Blue Book; and

  • the ESME shall undertake the conversion necessary to equate these values to ‘from_value’ and ‘to_value’ equivalents in accessing attribute 2 of any Profile generic object.
