universe package

The universe package provides options and primitive functions that are loaded into the Flux runtime by default and do not require an import statement.


  • inf represents a floating point value of infinity.


option now = system.time


now is a function option that, by default, returns the current system time.

now() vs system.time()

now() returns the current system time (UTC). now() is cached at runtime, so all executions of now() in a Flux script return the same time value. system.time() returns the system time (UTC) at which system.time() is executed. Each instance of system.time() in a Flux script returns a unique value.
