Issue 490: Add a flag to not serialize ctime
field
#718
Conversation
This request is for DL bookkeeper version upgrade. Because twitter's bk version doesn't include this change, so any ledgers written by new bk version will fail to be read by old version. To simplify the upgrade story, it is good to allow not serialize ctime field.
