Display time (using +FMT), or set time

        [-s,--set] TIME Set time to TIME

        -u,--utc        Work in UTC (don't convert to local time)

        -R,--rfc-2822   Output RFC-2822 compliant date string

        -I[SPEC]        Output ISO-8601 compliant date string

                        SPEC='date' (default) for date only,

                        'hours', 'minutes', or 'seconds' for date and

                        time to the indicated precision

        -r,--reference FILE     Display last modification time of FILE

        -d,--date TIME  Display TIME, not 'now'

        -D FMT          Use FMT for -d TIME conversion

Recognized TIME formats:

        hh:mm[:ss]

        [YYYY.]MM.DD-hh:mm[:ss]

        YYYY-MM-DD hh:mm[:ss]

        [[[[[YY]YY]MM]DD]hh]mm[.ss]

        'date TIME' form accepts MMDDhhmm[[YY]YY][.ss] instead
