6//! # Time block
7//!
8//! Use this block to get time monitoring in the status bar.
9//!
10//! Typical configuration:
11//!
12//! ```toml
13//! [time]
14//! ```
15//!
16//! ## Configuration options
17//!
18//! - `name`: Name of the block (must be unique)
19//! - `period`: Default update period in seconds (extra updates may occur on
20//!    event changes etc)
21//! - `format`: Strftime format string for specifying the time format
