Method and apparatus for adjusting event timestamp relating to clinical trial

A server apparatus comprising:

• a communication interface for transceiving information over a network;
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the server apparatus to:
• receive an event log corresponding to event entries of an electronic diary of a participant of a clinical trial, wherein the event log is generated in a client device, and the event log comprising at least two event entries, each of the at least two event entries associated with an event identifier and an event timestamp;
• determine a block of event entries within the event log, the block comprising a first event entry and a second event entry at least one of whose event timestamps are verified being correct in view of corresponding service timestamps of a server apparatus, wherein the first and the second event entry are arranged chronologically;
• and
• adjust the event timestamp of at least one of the first and the second event entry based on the timestamp verified being correct.

A computer program embodied on a computer readable non-transitory medium comprising computer executable program code, which when executed by at least one processor of an apparatus, causes the apparatus to:

• receive an event log corresponding to event entries of an electronic diary of a participant of a clinical trial, wherein the event log is generated in a client device, and the event log comprising at least two event entries, each of the at least two event entries associated with an event identifier and an event timestamp;
• determine a block of event entries within the event log, the block comprising a first event entry and a second event entry at least one of whose event timestamps are verified being correct in view of corresponding service timestamps of a server apparatus, wherein the first and the second event entry are arranged chronologically;
• and
• adjust the event timestamp of at least one of the first and the second event entry based on the timestamp verified being correct.
