Problem with iptc date format

[LGChaulo]

I have a problem when typing a date in iptc datas. 

If I tape "29/01/1959"

I get "1959-01-28T23:00:00"

Strange ! 

Technical infos : 

Mac Osx 10.14.6

Lightroom Classic 7.3

Why are you using LrC 7.3?

Why are you Typing in a Date?

Use the Change Capture Date option to Set the date and time of the image capture.

I'm typing a specific date since I digitalize old photos and I want to to put the exact date of the photo in the Iptc datas.
Yes, I can use the "Change Capture Date" option but I don't understand why when typing a date in the "creation date" field, I get a date slightly different than the one entered.
Before, I had not this problem.

Tks

Creation Date in the IPTC field is the FILE Create Date and Not the Capture date and time of when the Image was taken

[LGChaulo]

I don't mean the file creation date. My concern is about the image creation date which is… the date of creation of the image. Then you can enter or modify the date to indicate when the photo was created.
