Need help with M3U playlist set up

[1sikguy]

I have a couple of channels in my M3U playlist that not in sync with the guide. For example, Fight Network stream is 6 hours behind the EPG.
There is a keyword parameter that whan added to the playlist data will msync the stream and guide.

This parameter needs to be added to the #EXTINF list. the keyword is :

TVG-SHIFT='+6'

I need to know the syntax to add this command ( do I separate this by a space, or a comma when added on)

The data where I want to insert the parameter is:
eater is :

#EXTINF:0,Fight Network
#EXTVLCOPT:network-caching=1000
