Methods

Method Reference: datetime.exceltime

datetime: E = exceltime (T)
datetime: E = exceltime (T, dateType)

Convert datetime array to Excel serial date numbers.

E = exceltime (T) returns a double array E of the same size as T holding the Excel serial date number of each element, using the Excel 1900 date system, in which the fractional part represents the time of day. As in Excel, the year 1900 is treated as a leap year, so serial numbers on or after 1900-03-01 account for the nonexistent date 1900-02-29.

E = exceltime (T, dateType) selects the date system: '1900' (default) or '1904'. The 1904 system counts days from 1904-01-01 and has no leap-year anomaly.

The time zone of a zoned T is ignored; its wall-clock components are used. Not-A-Time (NaT) values are returned as NaN.
