FAQ
What is the difference between a 10-digit and 13-digit timestamp? A 10-digit timestamp is usually Unix seconds, while a 13-digit timestamp is usually Unix milliseconds.
Why are UTC and local time different? A Unix timestamp has no timezone. Timezone only matters when the timestamp is formatted as a date.
