Timefield is a Field API field for storing simple non-timezone time values, with an optional end time, utilizing a simple JQuery timepicker widget for input. Normally, you will want to use a Date field for all date/time values; however, this field is for use when you don't want to implement a Date field or have time values that are not dependent on the Gregorian Calendar, i.e., when Year,
Month granularity is irrelevant.
If you have repeating events that occur regularly on a weekly basis and wish to provide a simple way to display and store this logic, this field may provide the functionality you seek.
There are 3 storage options:
1. Single Time Value
2. Start Time - End Time
3. Start Time (optional End Time), Weekday Repeat
There are a few display options as well:
1. List Display
2. Duration Display (for times with End Time)
3. Table Display (for weekly repeat options)
Currently, this module supports rudimentary views integration.
** DIFFERENCES FROM DATE MODULE **
Date Module is awesome, huge, and complete. The Date Module (and it's children, Date API, Date Repeat API, etc.) provide a way to store specific date instances, dates that are inextricably linked to the Gregorian calendar. However, sometimes you have a very basic event, class, or other occurrence that has no relation to a year, or month. In these cases you do not need the complexity of complete date handling, you just need a way to store and display a more basic logic of an occurence like "Mondays at 8PM" or "Monday, Wednesday, Friday from 6PM-8PM".
