Timestamps are stored in the HLR DB in the new 'last_lu_seen' column of the 'subscriber' table, in UTC and in granularity of seconds. At present, osmo-hlr only records these timestamps but otherwise makes no use of them. Because the timestamps are stored in a human-readable form, they may already provide value to external processes which need this information. For example: sqlite> select imsi,last_lu_seen from subscriber; 901990000000001|2018-12-04 14:17:12 I didn't bother adding additional tests because the code added with this commit is already being exercised by several calls to db_subscr_lu() in db_test.c. This change requires a HLR DB schema update. Existing databases won't be upgraded automatically. However, osmo-hlr will refuse to operate with databases which are not upgraded.
