lsclocks - display system clocks
lsclocks [option]
lsclocks is a simple command to display system clocks. It allows to display information like current time and resolution of clocks like CLOCK_MONOTONIC, CLOCK_REALTIME and CLOCK_BOOTTIME.
-J, --json Use JSON output format. -n, --noheadings Don’t print headings. -o, --output list Specify which output columns to print. See the OUTPUT COLUMNS section for details of available columns. --output-all Output all columns. -r, --raw Use raw output format. -r, --time clock Show current time of one specific clock. --no-discover-dynamic Do not try to discover dynamic clocks. -d, --dynamic-clock path Also display specified dynamic clock. Can be specified multiple times. --no-discover-rtc Do not try to discover RTCs. -x, --rtc path Also display specified RTC. Can be specified multiple times. -c, --cpu-clock pid Also display CPU clock of specified process. Can be specified multiple times. -h, --help Display help text and exit. -V, --version Print version and exit.
Each column has a type. Types are surround by < and >. TYPE <string> Clock type. ID <number> Numeric clock ID. CLOCK <string> Name in the form CLOCK_ NAME <string> Shorter, easier to read name. TIME <number> Current clock timestamp as returned by clock_gettime(). ISO_TIME <string> ISO8601 formatted version of TIME. RESOL_RAW <number> Clock resolution as returned by clock_getres(2). RESOL <number> Human readable version of RESOL_RAW. REL_TIME <string> TIME time formatted as time range. NS_OFFSET <number> Offset of the current namespace to the parent namespace as read from /proc/self/timens_offsets.
