system.time() vs now()

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.

now() returns the current system time (UTC). now() is cached at runtime, so all instances of now() in a Flux script return the same value. {{% /note %}}
