Change of date of joining- dopt rules

The date of joining report is the criterion for giving increments.  The judgment of seniority has nothing to do with the increment date given as per the joining report.

Sir, Thank you so much for your kind reply.

Due to this five days delay in receiving the offer of appointment, I lost one increment from 2010.

Moreover, after 10 years from there I got MACP only on 02.07.2020. It should be on 28.06.2020. Now also increment is lost.

Whethet I can change my date of joining as per the offer of appointment, i.e. 20.06.2010 and thereby get MACP on 28.06.2020. How?

Any DoPT guideline is vaialble in this regard?

Please guide me.

When the employee has reported for duty, submitted a joining report, confirmation was passed on to the appointment authority, it is absolutely impossible to change the date of joining, and it is strange that such a proposal was from the Research officer.  The date may help in the future as your retirement will be longer, and if there is such regulation of revision of salaries in future, you may get a benefit.  Trying to alter public records amounts to falsification and fabrication and a criminal offense.  Most of the employers (who are themselves employees) intentionally send such orders to deny benefits to the new recruits.  They are under the impression that they are saving expenditure to Govt with their sincerity.
