TIMESTAMPINFO structure

Used by GetRtTimestampInfo to return information about the configured timestamp counter.

Syntax

typedef struct {
    QWORD    qwTimestampPeriodFs;
    DWORD    dwFlags;
} TIMESTAMPINFO, *LPTIMESTAMPINFO;

Fields

qwTimestampPeriodFs 
Set on return from GetRtTimestampInfo to the period of the timestamp counter in femtoseconds.
dwFlags 
Set on return to indicate the features of the configured timestamp counter.
Possible values include:
TS_SYNCHRONOUS
If this bit is set then the source has the same value on every node.
TS_COORDINATED
If this bit is set then the source increments at the same rate on every node, but might not contain the same value.
If both TS_COORDINATED and TS_SYNCHRONIZED are set the source has the same value on every node and increments at the same rate on every node. The source is guaranteed to return the same value at a given time from every node on the host.
If neither bit is set then the clock source is different on each node and is not guaranteed to increment at exactly the same rate.
