Crate hwclock [−] [src]
Hardware clock handling for linux
The hwclock
module provides a thin wrapper around kernel structs and
ioctls to retrieve the current time from the hardware clock and convert it
from and to a valid chrono
data structure.
extern crate chrono; extern crate hwclock; fn main() { use hwclock::HwClockDev; let rtc = HwClockDev::open("/dev/rtc0").expect("could not open rtc clock"); println!("{:?}", rtc); let time = rtc.get_time().expect("could not read rtc clock"); println!("{:?}", time); println!("Setting clock ahead 30 seconds"); let mut ct: chrono::NaiveDateTime = time.into(); ct += chrono::Duration::seconds(30); // convert back to RtcTime and set it let ntime = ct.into(); rtc.set_time(&ntime).expect("could not set rtc clock"); println!("Rereading..."); let time2 = rtc.get_time().expect("could not read rtc clock"); println!("{:?}", time2); }
