suggestion: option to specify date/time

[dicktyr]

considering the Pareto distribution in my own crontab
(i.e. most of the jobs run at a specific time of day)
I suggest an option to compactly specify time and/or date
(perhaps -h for human)

snooze -h 11:51 -> snooze -H 11 -M 51
snooze -h "Feb 9" -> snooze -m 2 -d 9
snooze -h "Feb 9 11:51:37" -> snooze -m 2 -d 9 -H 11 -M 51 -S 37

it seems reasonable to expect ordered input
(i.e. big to small: month day hour:minute:second)
and each unit can be easily parsed with the usual syntax
(alternation, range, star, repetition)

snooze -h string
string -> date time | date | time
date -> month d | month | d
month -> $(date +%b)*
time -> H:M | H:M:S

* also useful to allow date +%a for option -w and date +%b for option -m
date +%a -> locale's abbreviated weekday name (e.g., Sun)
date +%b -> locale's abbreviated month name (e.g., Jan)

For such a tool it may be reasonable to use things like GNU date's -d flag to synthesise the snooze command-line.

In one such script I do this to expose the date string to the user with the following:

# In bash you could use process substitution:
# read -r w h m s < <(date -d "$date" +'-w%w -H%H -M%M -S%S')
# snooze -v "$w" "$h" "$m" "$s"

date -d "$date" +'-w%w -H%H -M%M -S%S' | {
    read -r w h m s

    if snooze -v "$w" "$h" "$m" "$s"; then
        ...
    fi
}
