Help Center Help Center. The primary way to store date and time information is in datetime arrays, which support arithmetic, sorting, comparisons, plotting, and formatted display. The results of arithmetic differences are returned in duration arrays or, when you use calendar-based functions, in calendarDuration arrays. Specify numeric values for the year, month, day, hour, minute, and second components for the datetime. Change the value of a date or time component by assigning new values to the properties of the datetime array. For example, change the day number of each datetime by assigning new values to the Day property. Change the display format of the array by changing its Format property.

Work with these arrays in the same way that you work with numeric arrays. You can add, subtract, sort, compare, concatenate, and plot date and time values. You also can represent dates and times as numeric arrays or as text. Use datetime arrays to store date and time information. These arrays support arithmetic, sorting, comparisons, plotting, and formatted display. As of Rb, serial date numbers and date strings are not recommended for specifying dates and times. Use the datetime , duration , and calendarDuration data types instead. Follow these recommendations for updating your code. The Format property on datetime , duration , and calendarDuration arrays controls the display of values in each array. You can change the value of this property.

The following format does not display any time components. Start Hunting! TimeZone — Time zone '' default character vector string scalar.

For example, if dateType is 'posixtime' , then convertTo converts each element of D to the number of seconds that have elapsed since the epoch of January 1, , UTC. All numeric representations describe dates and times with respect to a point in time called an epoch. Computers typically measure time by the number of seconds or clock ticks since the specified epoch. For example, if you specify the epoch as 'Epoch','' , then each value in X represents the number of seconds before or after midnight on January 1, To display all the digits of the date numbers, set the numeric display format to longg.
