# Well... this seems relatively inconsistent. # <- :GL MODE #services +v GL
# Why does only setting some modes show a TS?
# This seems pretty relatively inconsistent - why do some commands have a TS at the end while others don't?
# Answer: the first syntax (MODE sent by SERVER) is used for channel bursts - according to Unreal 3.2 docs,
# the last argument should be interpreted as a timestamp ONLY if it is a number and the sender is a server.
# Ban bursting does not give any TS, nor do normal users setting modes. SAMODE is special though, it will
# send 0 as a TS argument (which should be ignored unless breaking the internal channel TS is desired).
# Also, we need to get rid of that extra space following the +f argument. :| # Also, we need to get rid of that extra space following the +f argument. :|
