A group A officer held on the strength of an Estt at Station A is on a long training at Station B (training extending for say about 6 months). He is half-way through the training and has 3 more months before its completion.

Meanwhile he is promoted to next higher Group A post and stands posted to Station C.

Instructions are received by his present unit at Station A to relieve him from their strength and that he will continue his training at Station B and report to his new Estt at Station C on completioin of his training after 3 months.

The question is - the officer concerned will report to Station C only after 3 months whereas he is being relieved of his present unit at Station A now. So, how to account for the gap of 3 months from now to the expected date of his reporting on completion of his training?

Any advise please?
