public abstract class date : PX.Data.BQL.BqlDateTime.Field<date> { }[PXDBDateAndTime(DisplayNameDate = "Date", DisplayNameTime = "Time", UseTimeZone = true)]
[PXUIField(DisplayName = "Date")]

public virtual DateTime? Date { get; set; }

Hi @aaghaei,

I have performed customization as you instructed but the results only display the Date. Cannot enter Time.

If you are using form then have a loot at the below

<px:PXTimeSpan DataField="Time" runat="server" ID="edtime" SummaryMode="true" InputMask="hh:mm" Width="100" ></px:PXTimeSpan>

If you are using grid then add from the data fields and it should come something like 

<px:PXGridColumn DataField="Date_Time" CommitChanges="true" ></px:PXGridColumn>

A friendly advise. I underestand people like to be productive and get the things done but always is a good idea to read through the materials or watch the videos to learn doing the work the right way. I bet you would get answer for all your questions in the materials.
