Since the subclassed panel's sizer is being set in the EVT_WINDOW_CREATE 
handler, on GTK it will happen after the panel has been added to its 
containing sizer, and so that sizer will not have current size info for 
the panel and so it assumes that it stays the small default size.  When 
the EVT_WINDOW_CREATE handler runs and the TimeCtrl is created and the 
panel is resized to fit, then it is essentially overriding what the 
sizer told it to do.  Since this new size (and nested sizer) is new 
information then you should tell the sizers above it in the hierarchy to 
redo their layout.  One way to do that is like this:

class WorkoutTime(wx.Panel):
     """Masked control for workout start/finish time"""

     def __init__(self):
         p = wx.PrePanel()
         # the Create step is done by XRC.
         self.PostCreate(p)
         self.Bind(wx.EVT_WINDOW_CREATE, self.OnCreate)

     def OnCreate(self, event):
         """Create masked control for time control"""
         self.timeCtrl = wx.lib.masked.TimeCtrl(self, fmt24hr=True,
                                                display_seconds=False)
         sizer = wx.BoxSizer(wx.VERTICAL)
         sizer.Add(self.timeCtrl)
         self.SetSizerAndFit(sizer)
         self.GetParent().Layout()
