The DateSeparator not follow DateFormatter

[quangchien99]

In the ChannelList screen (Image 1) -> the date for last message is display ok based on the DateFormatter.
However, in the MessageList screen (Image 2) -> the Date Separator is display differently ("4 days ago" instead of "Monday")

I checked the code in the SDK, the DefaultMessageDateSeparatorContent currently using DateUtils.getRelativeTimeSpanString to format the content.

Can the SDK make Date Separator follow DateFormatter or expose another Date Separator Formatter to custom?
