Override default DateTime 12:00 AM or 12:00PM to current Time? - customization

Question

As in my picture I have DateTime of SLA and Finish Date, and Finish Date is the same value of SLA but it allows user to add or change the DateTime. When I change the DateTime on Finish Date, it got the default value of Time was 12:00 PM or 12:00 AM. Is there any way to change the default time to current time? and will there be any impact if user changes the user locale format?
This is my UsrFinishDate default value:
UsrFinishDate (New Field)
[PXDBDate(PreserveTime = true)]
[PXUIField(DisplayName="Finish Date")]
protected void CRCase_UsrFinishDate_FieldDefaulting(PXCache cache, PXFieldDefaultingEventArgs e)
{
CRCase row = e.Row as CRCase;
CRCaseExt rowExt = PXCache<CRCase>.GetExtension<CRCaseExt>(row);
if (row == null || row.AssignDate == null) return;
if (row.ClassID != null && row.Severity != null)
{
var severity = (CRClassSeverityTime)PXSelect<CRClassSeverityTime,
Where<CRClassSeverityTime.caseClassID, Equal<Required<CRClassSeverityTime.caseClassID>>,
And<CRClassSeverityTime.severity, Equal<Required<CRClassSeverityTime.severity>>>>>
.Select(Base, row.ClassID, row.Severity);
if (severity != null && severity.TimeReaction != null)
{
e.NewValue = row.SLAETA;
e.Cancel = true;
}
}
if (row.Severity != null && row.ContractID != null)
{
var template = (Contract)PXSelect<Contract, Where<Contract.contractID, Equal<Required<CRCase.contractID>>>>.Select(Base, row.ContractID);
if (template == null) return;
var sla = (ContractSLAMapping)PXSelect<ContractSLAMapping,
Where<ContractSLAMapping.severity, Equal<Required<CRCase.severity>>,
And<ContractSLAMapping.contractID, Equal<Required<CRCase.contractID>>>>>
.Select(Base, row.Severity, template.TemplateID);
if (sla != null && sla.Period != null)
{
e.NewValue = row.SLAETA;
e.Cancel = true;
}
}
}
and this is my other event rowSelected:
protected void CRCase_RowUpdated(PXCache cache, PXRowUpdatedEventArgs e)
{
var row = e.Row as CRCase;
var oldRow = e.OldRow as CRCase;
CRCaseExt rowExt = PXCache<CRCase>.GetExtension<CRCaseExt>(row);
if (row == null || oldRow == null) return;
if (row.OwnerID == null)
{
row.AssignDate = null;
row.SLAETA = null;
rowExt.UsrFinishDate = null;
}
else if (oldRow.OwnerID == null)
{
row.AssignDate = PXTimeZoneInfo.Now;
if (row == null || row.AssignDate == null) return;
if (row.ClassID != null && row.Severity != null)
{
var severity = (CRClassSeverityTime)PXSelect<CRClassSeverityTime,
Where<CRClassSeverityTime.caseClassID, Equal<Required<CRClassSeverityTime.caseClassID>>,
And<CRClassSeverityTime.severity, Equal<Required<CRClassSeverityTime.severity>>>>>.
Select(Base, row.ClassID, row.Severity);
if (severity != null && severity.TimeReaction != null)
{
row.SLAETA = ((DateTime)row.AssignDate).AddMinutes((int)severity.TimeReaction);
rowExt.UsrFinishDate = ((DateTime)row.AssignDate).AddMinutes((int)severity.TimeReaction);
}
}
if (row.Severity != null && row.ContractID != null)
{
var template = (Contract)PXSelect<Contract, Where<Contract.contractID, Equal<Required<CRCase.contractID>>>>.Select(Base, row.ContractID);
if (template == null) return;
var sla = (ContractSLAMapping)PXSelect<ContractSLAMapping,
Where<ContractSLAMapping.severity, Equal<Required<CRCase.severity>>,
And<ContractSLAMapping.contractID, Equal<Required<CRCase.contractID>>>>>.
Select(Base, row.Severity, template.TemplateID);
if (sla != null && sla.Period != null)
{
row.SLAETA = ((DateTime)row.AssignDate).AddMinutes((int)sla.Period);
rowExt.UsrFinishDate = ((DateTime)row.AssignDate).AddMinutes((int)sla.Period);
}
}
}
}

Here is the definition of the field I added to the Case screen, note the PreserveTime = true which I think might be what you are missing.
public class CRCaseExt : PXCacheExtension<PX.Objects.CR.CRCase>
{
#region UsrFinishDate
[PXDBDate(PreserveTime = true)]
[PXUIField(DisplayName = "Finish Date")]
public virtual DateTime? UsrFinishDate { get; set; }
public abstract class usrFinishDate : IBqlField { }
#endregion
}
And here is an easy way to set the current time when the UsrFinishDate value is changed. Don't forget to set the CommitChanges for that field.
protected virtual void CRCase_UsrFinishDate_FieldUpdating(PXCache sender, PXFieldUpdatingEventArgs e)
{
CRCase currentCase = (CRCase)e.Row;
var caseExt = PXCache<CRCase>.GetExtension<CRCaseExt>(currentCase);
if (caseExt == null)
{
return;
}
e.NewValue = new DateTime(caseExt.UsrFinishDate.Value.Year,
caseExt.UsrFinishDate.Value.Month,
caseExt.UsrFinishDate.Value.Day,
DateTime.Now.Hour,
DateTime.Now.Minute,
DateTime.Now.Second);
}
