Frequently asked questions
What is a snowflake ID?
It is a 64-bit ID where the high bits hold a timestamp (offset from a custom epoch) and the low bits hold worker, process and sequence numbers.
Which epoch should I pick?
Use the Twitter epoch (2010) for Twitter/X IDs and the Discord epoch (2015) for Discord IDs, since they timestamp differently.
