Time and Date Calculations

First of all this date and time local value is given by the DateTimeGMT() function in number of days from 1/1/1970. So it really easy then to add or subtract a number of days onto this value, as the example shows on an addition of 60 days on the date of today. Then, in order to extract data from the result, you can use the StringfromGMTTimeToLocal() function which returns a string format of the date and time.

StringFromGMTTimeToLocal((DateTimeGMT( )+60)
