Here's part of the confusion: If you were to express the number of microseconds since 1970 in a decimal number, it would indeed take 16 digits. But uniqid() returns a /13 character string/, not a 13 digit number. The string is actually a hexadecimal number (and thus can express a greater range of values than a decimal number within those 13 characters). -John
Ahh! The moment when the penny drops. I was looking at the result as a number, not a string.
