Use PEXPIRETIME to read the absolute time at which a key will expire, as a Unix timestamp in milliseconds. The reply is -1 when the key exists but has no expiration and -2 when the key does not exist. It is the millisecond form of EXPIRETIME, and it reports a deadline rather than a remaining lifetime, which makes it the value to compare against a clock when you need to know exactly when something is due.

Syntax

Arguments

Important points

  • Negative integer replies are sentinel values, not durations or timestamps; see the response description for missing or persistent data.

Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.
Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

Examples

TCP examples use the TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
