Mr. Ritesh,
You can adopt the following format:
Notice
All employees are hereby advised to be punctual and regular in attending the office, mark their attendance in the muster roll, and adhere to the timings of reporting and leaving without fail. This is necessary for other functions like payroll management and updating leave records. The employees' cooperation in this regard is solicited.
Signature of competent authority
You can also visit the blog on talentmoon.com for guidelines on latecoming since it is a related issue.
