**Your software** My Mautic version is: 4.20 My PHP version is: 7.4.28 My Database type and version is: 10.3.34-MariaDB-log-cll-lve **Your problem** My problem is: Im trying to filter a segment dynamically. I have contacts with a DateTime field: ![contacts](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/7/7125726165e24d42f7e401a319cb1da35227d660.png) I would like for the contacts to populate a segment depending on the DateTime field. So my filter looks like this: ![filter](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/7/7848d60dec27b1ebb83ed4c0dc532d5de709dc5f.png) I read somewhere in the forum here that you can use ‘now’ to allow the filter to always have the correct date/time (maybe I misunderstood). But for the life of me, I cant get that to work. If I enter ‘now’, the actual DateTime gets saved (and the filter works great but is ofc static). I have tried =now, now() and so on, but I can’t get it to work. Anyone that can point me in the right direction? ---

Hi @pierre_a , thanks for answering. So, I have a list of recipients. Some of these recipients are in the US, some in Europe. I want to send the emails at the same time to all of them (let’s say noon). The easiest way would be to simply set a field in my original datasource with the time and date that the email should go out, and then when I import to Mautic, I have a field that is a datetime field that controls when the email will be sent. It might sound complex, but it’s the workflow that I prefer. I have solved this by writing a PHP script (triggered every 5 min with a cron), that updates the segment filter (basically sets the DateTime field to the current date and time), and that works great, but it’s a bit clumsy. Any ideas on how to achieve this out of the box? ---

Hello @CarlJohan, You write " want to send the emails at the same time to all of them (let’s say noon)." **Why it’s important for business?** Pierre ---

Hello @CarlJohan, I understand that this is a customer request. I think the problem is taken the wrong way. If the business use case is not understandable by the community, it will be difficult to imagine the best solution 😉 It is already possible to choose a sending window with dates and times in Mautic. Potentially with one Mautic instance per country (or geographical area). Does this fulfill the need? Pierre
