integer timestamp error

hey guys im trying to insert start_dtime and end_dtime fields as integers. im trying the attached code. but i run into this error. Types of property 'start_dtime' are incompatible. Type 'number' is not assignable to type 'SQL<unknown> | Placeholder<string, any> | Date | null | undefined'. i have attached both my schema and the code. can someone help me with this.
