My Question Is :
Is The time() [10 Digits Number (Seconds)] can Be Increased to 11 or 12 digits ?
The Purpose of Asking This Question is I am creating A uniq transaction id depending on that and with some other variable.. I have to maintain a Length of 18 Digits (Numbers only)
Edit : Note I dont want to make it longer.. As it increases to 11/12 digits i have to make the rest 7/8 digits dynamically .. Because i am using 2 randomiser for that last 7/8 digits
Edit2:
Will it make sense => rand(8 Digits) vs rand(3) + rand(3) + rand(2) For Collision Purpose ??

Unix epoch timestamps are supported in the following formats: 10 digit epoch time format surrounded by brackets (or followed by a comma).
No. epoch time is how time is kept track of internally in UNIX. It's seconds, counting upward from January 1st, 1970.
"2,147,483,647 – The End of Time [Unix]".
Here’s an example of how Unix timestamp is calculated from the wikipedia article: The Unix time number is zero at the Unix epoch, and increases by exactly 86 400 per day since the epoch. Thus 2004-09-16T00:00:00Z, 12 677 days after the epoch, is represented by the Unix time number 12 677 × 86 400 = 1 095 292 800.
Today’s timestamp requires 10 digits. What is Unix time format? How does Unix calculate time? What is a 13 digit timestamp? What is current Unix timestamp? What timestamp format is this? What is the epoch date today? How do I convert UNIX time to normal time? How do you calculate time duration? What is timestamp example?
How many digits is Unix time? - CompuHoy.com How many digits is Unix time? Today’s timestamp requires 10 digits. What is Unix time format?
On this date the Unix Time Stamp will cease to work due to a 32-bit overflow. Before this moment millions of applications will need to either adopt a new convention for time stamps or be migrated to 64-bit systems which will buy the time stamp a "bit" more time.
If you run date() with a time parameter containing the first 11 digit time you will see that you will not get 11 digits in a time() until
echo date('d/m/Y H:i:s', 10000000000);
RESULT
20/11/2286 17:46:40
If you think that your App will be running after that date you should worry about this situation, otherwise you dont need to worry or code for it.
PS I doubt PHP will exist or Intel come to that in 2286 :)
