I don't have information about what time was being used before the legal 
adoption of GMT.  The petition (March 1909) signed by ten members of the 
States of Deliberation of Guernsey called for adoption of GMT as well as 
for summer time (only the first part ended up entered into law), and says 
"As to the first, that the island time should be standardised, we 
apprehend that there will be little, if any, difference of opinion.  
Indeed, we think it likely that many will hear with surprise that there is 
at present no official standard time in Guernsey, and that at any moment 
questions might arise which would be difficult to settle in the present 
state of confusion.".
