Time and DateTime are displayed differently

[1minManager]

[Clock In] is a Time column. The data in the spreadsheet is “12:38:00”
[Clock in Timestamp column. The data in the spreadsheet is “15/07/2021 12:38:32”

Why are they displaying as 2 different time formats? If it matters, they are both being written by an action using TimeNow() and Now()

Dont really want to have a add another column and use a formula to sort this.
