Did you try the Datetime methods? if no please check the following:-

 

The following are the instance methods for Datetime.

1. Function Name - addDays     Argument - Integer addlDays where addlDays are the days to be added.

    Description- Adds the specified number of addlDays to a Datetime.
                                 For example:
                                        datetime myDate =datetime.newInstance(1960, 2, 17);
                                        datetime newDate = mydate.addDays(2);

 

2. Function Name - addHours  Argument - Integer addlHours where addlHours are the hours to be added.

    Description- Adds the specified number of addlHours to a Datetime.
                                 For example:
                                        datetime myDate =datetime.newInstance(1960, 2, 17);
                                        datetime newDate = mydate.addHours(1);

 

Alternatively you can extract the day, month, year, hour, second, minutes, then say increment or decrement the hour as per your requirement and create a new instance of the datetime.
