# Chapter 23. Package: Wallclock device

#### Macro name

CYGPKG_DEVICES_WALLCLOCK

#### Type

Boolean

#### Description

The wallclock device provides real time stamps, as opposed to the eCos kernel timers which typically just count the number of clock ticks since the hardware was powered up. Depending on the target platform this device may involve interacting with a suitable clock chip, or it may be emulated by using the kernel timers.
