We do not use their time stamp.
What time stamp are you using then?
We run a full bitcoin node and use it as the authoritative clock/transaction order
Actually blockchain.info has a very limited api and has gone down many times. We want our system based on the actual bitcoin blockchain, not a third party.
What is missing in the blockchain.info APIs? Your could create a lot of more trust, if you use a system (e.g. blockchain.info), we can easily follow. Even the clock there is always correct. I played ponzis for a longer time and till now i never saw any time lag. Sometimes the confirm takes longer, but the timestamp was always correct.
Why use a 3rd party api of the blockchain, when you can use the real blockchain? Take an address and compare the times and transaction orders between blockchain.info and blockr.io. They don't match 100%. We make sure our countdown timer is synched with our blockchain time. The true transaction order/time are directly taken from our node and displayed on our site.
Okay, but then your server should be always synced with the official time. At this moment it isn't. The time, you show in your lists differ from any atom clock. At this moment about 4-5 seconds. Not a big problem, if this difference would be always constant. But it would made me a little bit nervous, if it's fluctuating from hour to hour.
If you would refer to blockchain.info and say "new round starts, if blockchain time hits 3am (or whatever)", then everybody can check easily, if a deposit is IN or OUT.
But this is only a suggestion to create more trust, i will keep playing also with "your" server time, if we can rely on it.
First off, thank you for the suggestions. It is really appreciated. Here is an interesting link that shows how unpredictable the transaction timestamp is:
