io.delta.kernel.internal.util.TimestampUtils

public final class TimestampUtils
extends Object

Utilities for timestamp conversions that avoid overflow issues.

Note: ChronoUnit.MICROS.between() internally computes (seconds * 1_000_000_000) / 1000, where the intermediate nanoseconds value overflows for timestamps beyond ~292 years from epoch. These methods compute seconds * 1_000_000 directly to avoid overflow.
