No.
Code that does pretty-formatting in the DB should be changed to do so in the Tcl layer.
Here's the recommended way of doing things:
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"]
}
... or use your desired date/time format as the second argument to lc_time_fmt.
The only date format we should ever get out of the DB is ANSI dates.
