The commit also seems to change the event start time, which results in "invalid time range".

[mariobehling]

Oh, it seems this bug also exists now on eventyay.com.

[mariobehling]

Does not solve the issue.

Also I see that the pre-filled ticket sales time starts at 11pm and ends at 10pm.

The preview states ticket sales "will" start, but the time has passed already.

[shubham-padia]

The issue that you mentioned in the comment is a different issue #2806 which is yet to be solved.
This pr solves #2805 according to which default start time for the ticket sales should be according to the event timezone

[shubham-padia]

You can change the event timezone -> add a new ticket -> view start time of the ticket sales which will be according to the event timezone

[mariobehling]

Event timezone is Berlin UTC +1. Sales shows "This ticket's sale will start on January 01, 2017 11:50 PM". Time is: January 2, 00:08. Ticket sales should be available, but they are not. Which time is the ticket sales using? The issue is that ticket sales are not available even though they should in the timezone defined.

[shubham-padia]

The issue that you are mentioning is #2806 . This PR does not fix that.
This PR only fixes #2805 .

[shubham-padia]

I think i'll close this for now and provide changes for both #2806 and #2805

[mariobehling]

Ok, I think both need to be fixed together. Thank you for taking care!

[shubham-padia]

No problem 😄
