No matter the datetime value I received, I need to obtain two date time values from that date. The first one is the start of the day and the second one, the last time of the day. So, I receive this datetime value:

10/01/2006 13:00:56

I should obtain:

10/01/2006 00:00:00
10/01/2006 23:59:59

Do I need to convert the first datetime value to a string, manipulate that string, and convert it back to a datetime?
