Time[Bearbeiten]
Time instances represent a time-of-day (i.e. "hh:mm:ss" within a single day). Times are seldom used - usually timestamps are better suited.
Creation[Bearbeiten]
Time now => a time
- provides the current time of day
Arithmetic[Bearbeiten]
aTime addSeconds: nSeconds => a time
aTime addMinutes: nMinutes => a time
aTime addHours: nHours => a time
- to compute times
Accessing[Bearbeiten]
aTime hours => hours (0..24)
aTime minutes => hours (0..59)
aTime seconds => hours (0..59)
- to retrieve the hour, minute and second component:
Date[Bearbeiten]
Date instances represent a date (i.e. "dd-mm-yyyy"). Dates are seldom used - usually timestamps are better suited.
Timestamp[Bearbeiten]
Timestamp instances represent a particular point in time. (i.e. "dd-mm-yyyy hh:mm:ss").
TimeDuration[Bearbeiten]
Timeduration instances represent a time-delta. (i.e. seconds).
Date Protocol[Bearbeiten]
Date today => a date
- provides the current date
TimeDuration Protocol[Bearbeiten]
Timestamp Protocol[Bearbeiten]
Timestamp now => a time
- provides the current timestamp
