I have a condition like
let now = Clock::get()?.unix_timestamp as u64; if now <= account.start_time { // throw Error }
So if the user send the start time from the front end and then it compare the start time (account.start_time) to the cluster time (now). So there is always the 15 to 20 second difference of users start time and cluster time and it throw the error in a wrong condition. So How can I sync with as to remove this 15 to 20 second difference.
