    Hi yios

    Datetime type is actually a number where the integer part represents the days and the part behind the decimal separator a fraction of a day. 1/24 would be 1 hour, 1/(24*60) one minute. Based on this you can subtract 70 minutes simply by subtracting 70*/(24*60) from the datetime variable: 

    NewColumn =  Table1[TimeStamp] - 70*/(24*60)

    Then convert NewColumn to type DateTime again (the result of the operation will be a decimal number initially)
