|
|
|
The `universe` package provides options and primitive functions that are
|
|
loaded into the Flux runtime by default and do not require an
|
|
import statement.
|
|
|
|
## Constants
|
|
|
|
```js
|
|
inf
|
|
```
|
|
|
|
- **inf** represents a floating point value of infinity.
|
|
|
|
## Options
|
|
|
|
```js
|
|
option now = system.time
|
|
```
|
|
|
|
### now
|
|
|
|
`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.
|
|
|
