The set-date-window command allows specifying the rollover point on your system.
set-date-window {n} {(options)}
n | Two-digit number specifying the rollover point (year). If a non-numeric parameter is specified, an error message is returned. If no parameter is specified, the currently set rollover point is returned. | |
options | The following options are supported: | |
i | Suppress the output for this command. | |
x | Indicates that the value specified in n is expressed in hexadecimal format. |
The rollover point determines the numeric cutoff for which century (20th or 21st) is being referred to when representing the year in 2-digit format within a program. For example, if the rollover point is set to 30 (the default), specifying a 2-digit representation of the year between 00 and 29 means you are referring to the years 2000 - 2029. Conversely, specifying a 2-digit representation of the year between 30 and 99 means you are referring to the years 1930 - 1999.
The example below illustrates displaying the currently set rollover point. In this case, the default rollover point (30) is returned (as in, 01/01/1930).
>set-date-window Current Date Window:30
The example below illustrates setting the rollover point to 60 (as in, 01/01/1960).
>set-date-window 60 Current Date Window:60
