+NAME
+----
+tep_register_trace_clock - Registers the clock, used for the timestamp of
+the events.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+
+int *tep_register_trace_clock*(struct tep_handle pass:[*]_tep_, const char pass:[*]_trace_clock_);
+--
+
+DESCRIPTION
+-----------
+The _tep_register_trace_clock()_ function registers the clock, used for
+the timestamps of the events. When an event is recorded, a timestamp is attached
+to it. This timestamp comes from a specified clock. Supported clocks can be seen
+in tracefs/trace_clock, the selected one is in square brackets.
+The _tep_ argument is the trace event parser context. The _trace_clock_ argument
+is the name of the clock, the string is copied internally.
+
+RETURN VALUE
+------------
+The _tep_register_trace_clock()_ function returns 0 in case of success.
+If there is not enough memory to copy the _trace_clock_ string -1 is returned
+and errno is set to ENOMEM.
+
+EXAMPLE
+-------
+[source,c]
+--
+#include <event-parse.h>
+...
+struct tep_handle *tep = tep_alloc();
+...
+ if(tep_register_trace_clock(tep, "local") != 0) {
+ /* Failed to register the clock */
+ }
