/**

11
|
* Private implementation of hook_widget().
|
|
12
|
*
|
|
13
|
* The widget builds out a complex date element in the following way:
|
|
14
|
*
|
|
15
|
* - A field is pulled out of the database which is comprised of one or
|
|
16
|
* more collections of start/end dates.
|
|
17
|
*
|
|
18
|
* - The dates in this field are all converted from the UTC values stored
|
|
19
|
* in the database back to the local time. This is done in #process
|
|
20
|
* to avoid making this change to dates that are not being processed,
|
|
21
|
* like those hidden with #access.
|
|
22
|
*
|
|
23
|
* - If values are empty, the field settings rules are used to determine
|
|
24
|
* if the default_values should be empty, now, the same, or use strtotime.
|
|
25
|
*
|
|
26
|
* - Each start/end combination is created using the date_combo element type
|
|
27
|
* defined by the date module. If the timezone is date-specific, a
|
|
28
|
* timezone selector is added to the first combo element.
|
|
29
|
*
|
|
30
|
* - The date combo element creates two individual date elements, one each
|
|
31
|
* for the start and end field, using the appropriate individual Date API
|
|
32
|
* date elements, like selects, textfields, or popups.
|
|
33
|
*
|
|
34
|
* - In the individual element validation, the data supplied by the user is
|
|
35
|
* used to update the individual date values.
|
|
36
|
*
|
|
37
|
* - In the combo date validation, the timezone is updated, if necessary,
|
|
38
|
* then the user input date values are used with that timezone to create
|
|
39
|
* date objects, which are used update combo date timezone and offset values.
|
|
40
|
*
|
|
41
|
* - In the field's submission processing, the new date values, which are in
|
|
42
|
* the local timezone, are converted back to their UTC values and stored.
