Hi Mike, does this comment clarify something?

> [@Sending email at a specific time according to the time zone mentioned in the contact profile](https://forum.mautic.org/t/sending-email-at-a-specific-time-according-to-the-time-zone-mentioned-in-the-contact-profile/25790/3):

> Info I learned: Segment Emails (Newsletters) are sent according to Mautic Timezone (Author Timezone) Campaign Emails are sent according to contact Timezone Is the “Preferred Timezone” a custom contact field? Or is the default one that is used also by Mautic, when sending Campaign Emails?

Note: I used at first UTC inside Mautic. This was wrong, as this one does not consider Summer-Time. I changed to Berlin and it works ok.
