Date format in the Stack Exchange API
问题 When I query Stack Overflow (using it's API) to get some data (questions/answers/etc) I get the following JSON response: "down_vote_count": 0, "last_activity_date": 1300830790, "creation_date": 1300829790, The last_activity_date is a 10 digit number corresponding to some date in 1970. when I test today's timestamp (in Java if it's important) I get a 13 digit number. What is the format of the date timestamps in the responses I get? How do I translate it to regular Unix timestamp? Thanks. 回答1:
