Override or set in options timezone and country specific formats

Please add a possibility to customize timezone and country specific formats as for date, currency, etc.
For example, date from a MySql-Table is in format

Y-m-d

. In Droptables options, it should be possible to change the format to, for example,

d.m.Y,

so automatically every date in a front-end table is set to the customized format.
Same with currency. For example:
US format is 1.234,56.
Swiss format is 1'123.56

Or, in other way, it would be nice to override the view of a front-end table, so the format could be changed there.
For example:

if (strcmp($droptablefields->dbtablefield, 'datefiled') {

    change_format($droptablefields->dbtablefield, 'm.d.Y h:i');

}

or something similar.
