UnverifiedTIMESTAMP has a valid range of 1970 to 2038, while DATETIME can store dates from 1000 to 9999; the 2038 upper limit stems from its use of a 32-bit signed integer to record Unix timestamps.68% similarUnverifiedThe {{ $now }} expression can be used in system prompts to reference the current time to ensure accurate date calculations.64% similarUnverifiedAn absolute moment is a uniquely determined point on the UTC timeline, and both DateTimeOffset and timestamptz belong to this category of semantics.63% similarUnverifiedWhen the system clock is adjusted backward, calls to Date.now() or performance.now() in a Node.js process may generate non-monotonic timestamps, meaning a later event's timestamp is earlier than that of a prior event.63% similarUnverifiedThe feature of automatically landing on the correct date typically relies on natural language processing technology to perform temporal entity recognition on input content59% similar
