Subject: [PATCH] LP#1705524: Honor timezone of the acting library where
 appropriate

This is a followup to the work done in bug 1485374, where we added the ability
for the client to specify a timezone in which timestamps should be interpreted
in business logic and the database.

Most specifically, this work focuses on circulation due dates and the closed
date editor. Due dates, where displayed using stock templates (including
receipt templates) and used for fine calculation, are now manipulated in the
library's configured timezone. This is controlled by the new 'lib.timezone'
YAOUS, loaded from the server when required. Additionally, closings are
recorded in the library's timezone so that so that due date calculation is more
accurate. The closed date editor is also taught how to display closings in the
closed library's timezone. Closed date entries also explicitly record if they
are a full day closing, or a multi-day closing. This significantly simplifies
the editor, and may be useful in other contexts.

To accomplish this, we use the moment.js library and the moment-timezone addon.
This is necessary because the stock AngularJS date filter does not understand
locale-aware timezone values, which are required to support DST. A simple
mapper translates the differences in format values from AngularJS date to
moment.js.

Of special note are a set of new filters used for formatting timestamps under
certain circumstances. The new egOrgDateInContext, egOrgDate, and egDueDate
filters provide the functionality, and autogrid is enhanced to make use of
these where applicable. egGrid and egGridField are also taught to accept
default and field-specific options for applying date filters. These filters may
be useful in other or related contexts.

The egDueDate filter, used for all existing displays of due date via Angular
code, intentionally interprets timestamps in two different ways WRT timezone,
based on the circulation duration. If the duration is day-granular (that is,
the number of seconds in the duration is divisible by 86,400, or 24 hours worth
of seconds) then the date is interpreted as being in the circulation library's
timezone. If it is an hourly loan (any duration that does not meet the
day-granular criterium) then it is instead displayed in the client's timezone,
just as all other timestamps currently are, because of the work in 1485374.

The OPAC is adjusted to always display the due date in the circulating
library's timezone. Because the OPAC displays only the date portion of the due
date field, this difference is currently considered acceptable. If this proves
to be a problem in the future, a minor adjustment can be made to match the
egDueDate filter logic.

This work, as with 1485374 was funded by SITKA, and we thank them for their
partnership in making this happen!
