Schedule Publish Phases Separately Datepicker allows picking up previous date

Question

In the options for publishing, when I select the "Schedule Publish Phases Separately" and I select "Generate Publishable Content Now" and then "Place Content Online Later". The datepicker allows the previous date to be selected for "Place Content Online Later".

Is this a known issue? Anybody experienced the same issue? This happens only with "Schedule Publish Phases Separately" option. On the "Publish Content Later" option I am not able to pick a previous date.

We are on Tridion 2013 SP1.

Update:

After few hit and trials, I found the exact steps to reproduce. This is happening in all browsers. Here are the exact steps:

1. On first item schedule using the Schedule Phases Separately, it works as expected and does not allows to select the previous date.
2. But after that if we schedule another item, the datepicker is already filled with the date and then it allows to pick up a previous date (any previous date) in the Schedule Publish Phases Separately option.

It is reproducible on Chrome, IE, FF or Safari. If I pick up a previous date, the transaction is executed immediately.

Tridion Support team have been able to reproduce the same and confirmed that this a defect and have sent it over to R&D. It is happening in 2013 SP1 and SP1 HR1 as well. Once I receive a hotfix, I will update my answer.

As a word of caution, I will like to suggest everyone to watch out date selected because I noticed this behavior when I was trying to set a time sensitive publish for the next day 1200, but by default the previous day was selected and I just went ahead with time changes assuming it cannot be a back date. When the jobs started to go from "Scheduled for Publish" and forward to the next stage is when I realized there is a problem and I deleted the jobs from the queue, just in time!!
