Frequently asked
Seconds or milliseconds · how do I tell?
Length. Current time is ~1.8 billion in seconds (10 digits) and ~1.8 trillion in milliseconds (13 digits). The converter auto-detects by magnitude, so either pastes correctly.
What is the year-2038 problem?
Signed 32-bit timestamps overflow on January 19, 2038. Modern systems store 64-bit timestamps and are fine · but legacy embedded systems and old database columns may still be exposed.
