The date argument in parentheses can be seconds (or any function that returns seconds), or any date-time
literal value. For example, both of the following expressions return the same value:
Long Date(3388649872);
Long Date(19May2011);
"Thursday, May 19, 2011"
Note: Long Date() and Abbrev Date() values are formatted according to your computer’s regional
settings.
Extract Parts of Dates
You can extract parts of date values using the functions Month(), Day(), Year(), Day Of Week(), Day
Of Year(), Week Of Year(), Time Of Day, Hour(), Minute(), and Second(), which all return
integers. If today is March 24th, 2011, each of the following examples returns the 144th day of the year:
Day of Year(Today());
Day of Year(24May2011);
Day of Year(Date MDY(5,24,2011));
144
Example
A data table column named Date contains date-time values that are formatted as "m/d/y". You want to
create a column that shows only the time. In the following script, the second column’s formula extracts the
time of day from the Date value in the first column.
New Table( "Assembly Tests",
Add Rows( 1 ),
New Column( "Date",
Numeric, Continuous,
Format( "m/d/y" ),
Set Values( [3389083557] )
),
New Column( "Time",
Numeric, Continuous,
Formula(Format(Time Of Day( :Date ), "h:m:s"))
)
);
