JS : Returning a date -17h

//Convert the date in a millisecond timestamp 
const date1 = new Date("2021-01-01 00:00:00").getTime()

//We remove 17 hours to Date1 and put the result in Date2 
                                    //17 * 60 (min) * 60 (sec) * 1000 (millisecond timestamp)
 let date2 = date1 - 17*60*60*1000
