SysNativeTimeStamp Struct Reference

#include <evo/impl/systime.h>

Detailed Description

Holds a system timestamp as native (platform specific) fields.

• This is used to get and store the current current date/time efficiently, then later convert to a DateTime (which has some overhead)

typedef struct timeval Fields

Constructor & Destructor Documentation

SysNativeTimeStamp() [1/2]

SysNativeTimeStamp ( )

inline

Constructor.

• This does not initialize current fields – use set() or set_utc()

SysNativeTimeStamp() [2/2]

SysNativeTimeStamp ( const SysNativeTimeStamp &  src )

inline

Copy constructor.

Parameters

src	Source to copy

Member Function Documentation

convert_local_dt()

void convert_local_dt ( DT &  dt ) const

inline

Convert current date/time to DateTime holding Local Time, including timezone offset.

Template Parameters

DateTime

type, inferred from argument

Parameters

dt	Stores converted date/time [out]

convert_local_dt_notz()

void convert_local_dt_notz ( DT &  dt ) const

inline

Convert current date/time to DateTime holding Local Time, without storing timezone offset.

Template Parameters

DateTime

type, inferred from argument

Parameters

dt	Stores converted date/time [out]

convert_utc_dt()

void convert_utc_dt ( DT &  dt ) const

inline

Convert current date/time to DateTime holding UTC.

Template Parameters

DateTime

type, inferred from argument

Parameters

dt	Stores converted date/time [out]

get_msec()

int get_msec ( ) const

inline

Get current fractional second value in milliseconds.

Returns

Milliseconds

get_nsec()

long get_nsec ( ) const

inline

Get current fractional second value in nanoseconds.

Returns

Nanoseconds

get_unix_timestamp()

int64 get_unix_timestamp ( ) const

inline

Get current date/time as Unix timestamp.

• Unix timestamps are seconds since Jan 1 1970 (not counting leap seconds)

Returns

Unix timestamp, never negative, 0 for dates before 1970

operator=()

SysNativeTimeStamp& operator= ( const SysNativeTimeStamp &  src )

inline

Assignment operator.

Parameters

src	Source to copy

Returns

This

set()

void set ( )

inline

Set as null/invalid timestamp.

set_utc()

void set_utc ( )

inline

Set to current date/time (UTC).

Member Data Documentation

SEC_PER_MIN
