```{index} single: compile_date; Config function ``` ```{index} single: Config::compile_date; Perl function ``` # compile_date Return a one-line description of when and with what the interpreter was built. ## Synopsis ```perl use Config; print Config::compile_date(), "\n"; ``` ## What you get back A scalar string such as `Compiled with rustc 1.xx (...)`. The exact format is stable enough to log but not intended for machine parsing; prefer `%Config` entries for structured fields. ## Differences from upstream - Describes the Rust toolchain that built pperl rather than a C compiler invocation date. Callers that only print the string are unaffected; callers that parse it for a specific date layout need to adapt.
