Century (-D)

Use the Century execution command (-D) to specify the start of a 100-year range used to supply a missing century portion for a Date & Time. This command is useful for the transition to the year 2000 so that dates with a YYMMDD format can be interpreted properly for the correct century.

-D[ccyy|0]
Option
Description

Turn off the Century execution command.

For example, if you specify -D1960, a YYMMDD-formatted date between 60mmdd and 99mmdd is interpreted as having a century value of 19. Dates between 00mmdd and 59mmdd are interpreted as having a century value of 20. In this example, data with a date of 580101 is assigned a century of 20; however, data with a date of 600101 is assigned a century of 19.
