Client dial time imported wrong in Cisco's Contact Center outbound campaign - cisco

Question

Using Cisco's Unified Contact Center Express 9.0.2-11001-24 I'm attempting to create new outbound campaign with a set of clients.
Importing the clients via the REST API:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<campaignContacts>
<campaign name="test">
<refURL>https://host:8443/adminapi/campaign/23</refURL>
</campaign>
<csvdata>
Account Number, First Name, Last Name, Phone1, Phone2, Phone3, Dial Time
1, John, Doe, 1234, 5678, 9012, 14:05
2, Joe, Smith, 2222, 3333, 4444, 14:24
</csvdata>
</campaignContacts>
is successful but querying the contacts with
https://host:8443/adminapi/campaign/23/contacts
gives:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<campaignContacts>
<campaign name="test">
<refURL>https://host:8443/adminapi/campaign/23</refURL>
</campaign>
<csvdata>
account number, first name, last name, phone1, phone2, phone3, dial time
1, John, Doe, 1234, 5678, 9012, 10:5
2, Joe, Smith, 2222, 3333, 4444, 10:24
</csvdata>
</campaignContacts>
The dial time is not imported correctly and the contact is called directly.
I've tried using HHmm instead of HH:mm but that doesn't work either.
The documentation HERE clearly says that:
DialTime field is used to specify the time to dial a number for individual contacts on the current date. The format to be used for this field is HH:MM. For example, to specify the dialing time as 08:25 am, the dial time field value should be 08:25 and for 03:45 pm, the dial time field value should be 15:45.
Any ideas?

Answer 1

Okay, after some testing it turned out that DialTime is actually working correctly. The contacts weren't called on time because of the Callback Time Limit setting of the campaign.
Querying the contacts with https://host:8443/adminapi/campaign/{id}/contacts is broken and shows wrong DialTime values
