SiliconID - a better/replacement of UID Capablity: Uniqueness, Limited Length along with Sortability

i used to use a function using php to generate randome string, intent to use replacement of UID, so i can use this on DOS system (max 8 char constrain)

i needed Uniqueness, Limited Length along with Sortability. Options i had on dos @echo off set /a num=%random%%%100000000 echo %num% on linux/bsd cat /proc/sys/kernel/random/uuid | cut -c1-8 date +%s%N | sha256sum | base64 | head -c 8

lets re-implement SiliconID maintaining Uniqueness to reduce collisions having Limited Length along with Sortability

keeping in mind: 1. Custom Epoch is supported by every modern programming Language. 2. Can start with 2020 3. Timestamp with mili second 4. [timestamp (10 digits)] + [random number (5 digits)] = 15-digit decimal 5. Encoding 14-digit decimal into Base-62 gives exactly 8 chars
