i want to differentiate users device(computers,mobiles) based on device time (accurately down to milliseconds).no two devices will have same time accurately in milliseconds.
php can generate server time as php timestamp.
my logic approach:
-> first detecting user device time though js.
-> sending it to server for comparing with php timestamp
-> after comparing will generate a "difference string" it will be used to differentiate devices.
my approach may be wrong because few seconds will take to pass js var to server.so it will lead to error.
i will be really thankful to him who will solve this issue.
