I don't know if there really is a special magical format for that. I needed to code at least in refresh:

Public oForm
oForm = Createobject('myForm')
oForm.Show()

Define Class myForm As Form

  Add Object myLabel As Label
  Add Object myTimer As Timer With Interval=1000

  Procedure Init
    Set Seconds On
    This.myLabel.Caption = "=ttoc(DATETIME())"
  Endproc

  Procedure myTimer.Timer
    Thisform.Refresh()
  Endproc

  Procedure Refresh
    With This.myLabel
      .Caption = .ReadExpression('Caption')
    Endwith
  Endproc
Enddefine
