Frequently Asked Questions
January 1, 2015 (the custom epoch used by Twitter's original Snowflake implementation), with the millisecond offset since then shifted into the upper bits of the 64-bit ID.
No — they're fixed constant values, not read from any real machine or datacenter identifier, since this tool runs in your browser rather than as part of a real distributed system. Only the timestamp and the random sequence number actually vary.
Not strictly — a real Snowflake deployment relies on unique machine IDs across nodes plus a strictly incrementing per-millisecond counter to guarantee uniqueness; this tool uses a random sequence number instead, which is very unlikely to collide but isn't a formal uniqueness guarantee.
No — generation happens entirely in your browser.
