Default token lifetime for relying party trusts?

I have found conflicting information on the net about what the default value is for TokenLifetime for a relying party trust in ADFS 2.0.  This (http://technet.microsoft.com/en-us/library/cc782865(v=ws.10).aspx) says 480 minutes, but looks like it might apply to ADFS 1.0.  This (http://technet.microsoft.com/en-us/library/gg188586.aspx) says 60 minutes and the information looks more recent. I've seen other sites that claim the value is 600 minutes (http://stackoverflow.com/questions/14867613/adfs-2-0-time-out-and-relation-between-freshness-value-tokenlifetime-and-webssol). All very confusing. 

All my relying party trusts have the TokenLifetime set to 0 (so default settings) and I need to know how long this token is set for.  Thanks.
