Interbase. The issue is that Firedac writes datetime fields with milliseconds. IBX does not. So, when my old apps try and modify a record, it thinks the record has changed because when it searches for the record to change it cannot find it because the datetime does not match (off by the milliseconds)...
When we change ALL legacy apps to Firedac the problem would disappear - but who knows when that may be. So I am looking for a way to make firedac not send the milliseconds...
