t:schedule HeaderDateFormat locale problems

Hi, i'm using t:schedule from tomahawk and i've a problem:

property headerDateFormat takes the Locale from the Server (for example, English) and, if i want to use the context viewroot to format the date it's imposible.

For example: if my navigator's language is in spanish, t:schedule shows me the headerDateFormat in english beacause is the Locale from the Server where is my application.

I saw code from tomahawk t:schedule --> AbstractScheduleRenderer when i use the headerDateFormat property :

if ((pattern != null) && (pattern.length() > 0))
{
format = new SimpleDateFormat(pattern); --> it would be ok if --> new SimpleDateFormat(pattern, context.getViewRoot.getLocale());
}

Is there any possiblity without modifying AbstractScheduleRenderer code to localize the headerDateFormat property ?

Thanks
