Hello Andrew,

Apologies in advance for my non-native English — please bear with me :)

Thanks for the clarification on AS13. After thinking it through, I agree that 
to_start_time is a better name than by_start_time. Your reasoning is 
convincing: 
by_duration computes a relative time (now - duration), while the new policy 
anchors to an absolute, server-recorded timestamp (the group creation time). 
The to_* prefix correctly conveys “seek to a fixed point”.

Best Regards,
Jiunn-Yang
