# usage: alarm +relativetime [msg]
# alarm absolutetime [msg]

# where:
# relativetime is a number in seconds or a number followed by
# a unit character (s for seconds, m for minutes, h for hours), e.g., +2h
# absolutetime is a precise time for the alarm, e.g., 3pm
# msg is an optional text message to be displayed when the alarm fires.
