Find datetime in .xql files. Use command line tools to find suspect SQL code:
grep -r "to_char.*H" * grep -r "to_date.*H" *
In SQL statements, replace the format string with the ANSI standard format, YYYY-MM-DD HH24:MI:SS and change the field name to *_ansi so that it cannot be confused with previous, improperly formatting fields. For example,
to_char(timestamp,'MM/DD/YYYY HH:MI:SS') as foo_date_pretty
becomes
to_char(timestamp,'YYYY-MM-DD HH24:MI:SS') as foo_date_ansi
In TCL files where the date fields are used, convert the datetime from local server timezone, which is how it's stored in the database, to the user's timezone for display. Do this with the localizing function lc_time_system_to_conn:
set foo_date_ansi [lc_time_system_to_conn $foo_date_ansi]
When a datetime will be written to the database, first convert it from the user's local time to the server's timezone with lc_time_conn_to_system.
When a datetime field will be displayed, format it using the localizing function lc_time_fmt. lc_time_fmt takes two parameters, datetime and format code. Several format codes are usable for localization; they are placeholders that format dates with the appropriate codes for the user's locale. These codes are: %x, %X, %q, %Q, and %c.
set foo_date_pretty [lc_time_fmt $foo_date_ansi "%x %X"]
User locale is a property of ad_conn, ad_conn locale. The request processor sets this by calling lang::conn::locale, which looks for the following in order of precedence:
Use user preference for this package (stored in ad_locale_user_prefs)
Use system preference for the package (stored in apm_packages)
Use user's general preference (stored in user_preferences)
Use Browser header (Accept-Language HTTP header)
Use system locale (an APM parameter for acs_lang)
default to en_US
For ADP pages, message key lookup occurs in the templating engine. For TCL pages, message key lookup happens with the _ function. In both cases, if the requested locale is not found but a locale which is the default for the language which matches your locale's language is -found, then that locale is offered instead.
