Starting with OpenACS 5.0 and the introduction of acs-lang,
we recommend retrieving date/time information from the database in
ANSI format and then using lc_time_fmt to format it for display.
Example 9.1. Getting datetime from the database ANSI-style
db_multirow -extend { mydate_pretty } {
select to_char(mydate, 'YYYY-MM-DD HH24:MI:SS') as mydate_ansi,
...
...
} {
set mydate_ansi [lc_time_system_to_conn $mydate_ansi]
set mydate_pretty [lc_time_fmt $mydate_ansi "%x %X"]
}
