How do I read the time field from the json-rpc calls from bitcoind? The JSON-RPC would return the time in this format "time": 1346289025. How exactly do I read it? I don't know what  kind of format it is. So what time is 1346289025?
It's unix time, the number of seconds since January 1, 1970. Your programming language probably has an easy standard way of converting it to a date.
