What is a resolution of jiffie in Linux Kernel?

according to current timer source (`cat /sys/devices/system/clocksource/clocksource0/current_clocksource`), Linux uses TSC and has nanosecond resolution

according to <http://lxr.free-electrons.com/source/include/linux/jiffies.h> jiffie is not smaller than 1us, but can be larger.

Is there a way to determine its current resolution.
