Owning Class: time
Requires: MathScript RT Module
n = date_to_num(s)
n = date_to_num(v)
n = date_to_num(s, pivotyear)
n = date_to_num(y, m, d)
Converts a time in string or vector format to a double-precision, floating-point number. n = date_to_num(s) is equivalent to n = date_to_num(s, -1).
|s||Specifies a time in string format.|
|pivotyear||Provides additional information about the century if you use the form yy in s. If you specify a pivotyear, LabVIEW considers s to be a time in pivotyear or the 99 years that follow pivotyear. For example, the result of date_to_num('18-Oct-04', 1900) is equivalent to the result of date_to_num('18-Oct-1904'). However, if you do not specify pivotyear, or if pivotyear is less than 0, LabVIEW considers s to be within a century centered on the current year, or the current year plus or minus 50 years. For example, the result of date_to_num('18-Oct-04') is equivalent to the result of date_to_num('18-Oct-2004').|
|v||Specifies a time in vector format.|
|y||Specifies the year. y is a matrix.|
|m||Specifies the month. m is a matrix.|
|d||Specifies the day. d is a matrix.|
|n||Returns the time as a double-precision, floating-point number.|
y, m, and d must be matrices of the same size, or any can be a scalar.
