    Convert epoch time both ways

    Developer-focused timestamp searches usually need fast bidirectional conversion: paste an epoch value and get UTC/local dates, or enter a date and get seconds, milliseconds, microseconds and nanoseconds.

    t_unix is epoch seconds, T is the selected instant in milliseconds, and T_epoch is 1970-01-01 00:00:00 UTC.

    ms is milliseconds and s is Unix timestamp seconds.

    Seconds, milliseconds and precision

    • 10-digit values are usually seconds.
    • 13-digit values are usually milliseconds, common in JavaScript.
    • 16- and 19-digit values are common in high-precision logs.
    • JavaScript Date stores milliseconds; microsecond and nanosecond remainders are shown separately.
    • Unix timestamps represent an instant; time zones only affect display.
