Ext.Date.format() only prints locale strings?

I have Date objects that were set using a UTC time and I want to recover that time when formatting them using Ext.Date.format(). A very simple example demonstrates that Ext.Date.format() will print a locale string.

Code:

---

var d = new Date('1998-04-15T20:00:00.0000Z');



d.toUTCString();

// "Wed, 15 Apr 1998 20:00:00 GMT"



Ext.Date.format(d, 'H:i')

// "16:00"



Ext.Date.format(Ext.Date.parse('1998-04-15T20:00:00.0000Z', 'c'), 'H:i')

// "16:00"

---

I need my time string formatted a certain way, and Ext.Date.format() is extremely helpful in that regard. However, I need it to format the date as a UTC string, not a locale string. Relative to the above example, I need a way to output the string "20:00" instead of the string "16:00".



Is this not supported? I will just have to concatenate the outputs from d.getUTCHours() and so forth?
