A date string may contain items indicating calendar date, time of day, time zone, day of week, relative time, relative date, and numbers. An empty string indicates the beginning of the day. The date string format is more complex than is easily documented here but is fully described in the info documentation. . coreutils: Copyright (C) 2023 Free Software Foundation, Inc. 3+: 3 . : . , . ,,info '(coreutils) date invocation'" ; 3 . . , - TODO <>. coreutils 9.4 2024 DATE(1)
