public class TPMS_CLOCK_INFO
extends TpmStructure

This structure is used in each of the attestation commands.

Field Summary

Fields

Modifier and Type	Field and Description
long	clock time value in milliseconds that advances while the TPM is powered NOTE The interpretation of the time-origin (clock=0) is out of the scope of this specification, although Coordinated Universal Time (UTC) is expected to be a common convention.
int	resetCount number of occurrences of TPM Reset since the last TPM2_Clear()
int	restartCount number of times that TPM2_Shutdown() or _TPM_Hash_Start have occurred since the last TPM Reset or TPM2_Clear().
byte	safe no value of Clock greater than the current value of Clock has been previously reported by the TPM.

Field Detail

clock

public long clock

time value in milliseconds that advances while the TPM is powered NOTE The interpretation of the time-origin (clock=0) is out of the scope of this specification, although Coordinated Universal Time (UTC) is expected to be a common convention. This structure element is used to report on the TPM's Clock value. The value of Clock shall be recorded in non-volatile memory no less often than once per 222 milliseconds (~69.9 minutes) of TPM operation. The reference for the millisecond timer is the TPM oscillator. This value is reset to zero when the Storage Primary Seed is changed (TPM2_Clear()). This value may be advanced by TPM2_ClockSet().

resetCount

public int resetCount

number of occurrences of TPM Reset since the last TPM2_Clear()

restartCount

public int restartCount

number of times that TPM2_Shutdown() or _TPM_Hash_Start have occurred since the last TPM Reset or TPM2_Clear().

safe

public byte safe

no value of Clock greater than the current value of Clock has been previously reported by the TPM. Set to YES on TPM2_Clear().

Constructor Detail

TPMS_CLOCK_INFO

public TPMS_CLOCK_INFO(long _clock,
                       int _resetCount,
                       int _restartCount,
                       byte _safe)

This structure is used in each of the attestation commands.

Parameters:

_clock - time value in milliseconds that advances while the TPM is powered NOTE The interpretation of the time-origin (clock=0) is out of the scope of this specification, although Coordinated Universal Time (UTC) is expected to be a common convention. This structure element is used to report on the TPM's Clock value. The value of Clock shall be recorded in non-volatile memory no less often than once per 222 milliseconds (~69.9 minutes) of TPM operation. The reference for the millisecond timer is the TPM oscillator. This value is reset to zero when the Storage Primary Seed is changed (TPM2_Clear()). This value may be advanced by TPM2_ClockSet().

_resetCount - number of occurrences of TPM Reset since the last TPM2_Clear()

_restartCount - number of times that TPM2_Shutdown() or _TPM_Hash_Start have occurred since the last TPM Reset or TPM2_Clear().

_safe - no value of Clock greater than the current value of Clock has been previously reported by the TPM. Set to YES on TPM2_Clear().

TPMS_CLOCK_INFO
