In an order, the department said all officers and officials are directed to report to their offices by 9.30 am and leave by 6.30 pm.
The move comes after it was noticed that most officials of the social welfare department were not punctual in attending office.
"The officers/officials who have not registered themselves in the bio-metric system shall get themselves registered in the bio-metric attendance system without any fail, failing which disciplinary action will be initiated against them," the order stated.
In December, Delhi Chief Secretary M M Kutty had also warned bureaucrats of strict action if they came to after later than 9.45 am.
