countdown showing days +1

[metalllus]

Hi, folks, I am using this config

{{ stopTime: publishTimestamp().toDate(), format: 'dd HH mm ss' }}

No matter how far the publish timestamp is into the future I always get days + 1 (i.e showing 1 day left when there should be 0, or 2 when there should be 1). The hours, minutes and seconds are shown correctly.

Angular version: 18.2
ngx-countdown version: 18.0.0

I must be doing some silly mistake somewhere, please help.

Maybe you can find inspiration from this example.
