Scheduling

Schedule an alarm for an explicit local time with at:

clck at 2:50pm
clck at "tomorrow at 9am"
clck at "June 12 at 09:00"

clck resolves the expression in the system's local IANA time zone and shows the full local date, time, UTC offset, and time-zone name before asking for confirmation.

Past targets are rejected. Local times that are nonexistent or ambiguous during daylight-saving transitions are also rejected instead of being guessed.

Extract Times from Text

Use from-text to find explicit dates and times in text:

clck from-text
printf 'Meet tomorrow at 9am\n' | clck from-text
printf 'Choose June 12 at 09:00 or June 12 at 14:30\n' | clck from-text

Interactive multiline input ends when you enter a single . on its own line. When multiple valid targets are found, you must select one explicitly.

Piped input uses the controlling terminal for selection and confirmation when one is available. Without a controlling terminal, candidates are printed and the command exits without starting an alarm.
