Constructor & Destructor Documentation

◆ Timestamp() [1/6]

Timestamp ( )

Constructs an uninitialized instance.

◆ Timestamp() [2/6]

Timestamp ( TotalSeconds seconds,
Nanosecond nanosecond )
inline

Initializes from seconds and nanoseconds since Jan 1, 0001, 00:00:00.

Definition at line 237 of file Timestamp.h.

◆ Timestamp() [3/6]

Timestamp ( TotalSeconds seconds,
Picosecond picosecond )
inline

Initializes from seconds and picoseconds since Jan 1, 0001, 00:00:00.

Definition at line 245 of file Timestamp.h.

◆ Timestamp() [4/6]

Timestamp ( Year year,
Month::Enum month,
Day day,
Hour hour = 0,
Minute minute = 0,
Second second = 0,
Nanosecond nanosecond = 0 )

Initializes date-time from all details.

◆ Timestamp() [5/6]

Timestamp ( Year year,
Month::Enum month,
Day day,
Hour hour,
Minute minute,
Second second,
Picosecond picosecond )

Initializes date-time from all details.

◆ Timestamp() [6/6]

Timestamp ( TotalNanoseconds unixTimestampNanoseconds)
explicit

Initializes from nanoseconds since Jan 1, 1970, 00:00:00 (Unix epoch).

Member Function Documentation

◆ date()

void date ( YearMonthDay & ) const

Returns the date part of the timestamp.

◆ day()

Day day ( ) const

The current day of month. Valid values are 1 through 31.

◆ hour()

Hour hour ( ) const

The current hour. Valid values are 0 through 23.

◆ local()

Timestamp local ( )
static

Returns the current local time.

Note
The timestamp resolution depends on capabilities of an operating system.

◆ microsecond()

Microsecond microsecond ( ) const
inline

The current microsecond. Valid values are 0 through 999999.

Definition at line 268 of file Timestamp.h.

◆ millisecond()

Millisecond millisecond ( ) const
inline

The current millisecond. Valid values are 0 through 999.

Definition at line 261 of file Timestamp.h.

◆ minute()

Minute minute ( ) const

The current minute. Valid values are 0 through 59.

◆ month()

Month::Enum month ( ) const

The current month.

◆ nanosecond()

Nanosecond nanosecond ( ) const
inline

The current nanosecond. Valid values are 0 through 999999999.

Definition at line 275 of file Timestamp.h.

◆ operator!=()

bool operator!= ( const Timestamp & ) const

Compares the instance with another one.

◆ operator+=()

Timestamp & operator+= ( const TimeSpan & )

Increases the instance by time span.

◆ operator-()

TimeSpan operator- ( const Timestamp & )

Calculates the time interval between two time points.

◆ operator-=()

Timestamp & operator-= ( const TimeSpan & )

Decreases the instance by time span.

◆ operator<()

bool operator< ( const Timestamp & ) const

Tests whether the instance is less than another one.

◆ operator==()

bool operator== ( const Timestamp & ) const

Compares the instance with another one.

◆ parse()

Timestamp parse ( const std::string & ,
TimestampFormat::Enum = TimestampFormat::YYYYMMDDHHMMSSNsec )
static

Parses the timestamp from its text presentation assuming it's in the specified format ("YYYYMMDD-HH:MM:SS.sssssssss" by default).

◆ parseWithoutFormat()

Timestamp parseWithoutFormat ( const std::string & )
static

Parses the timestamp from its text presentation. The format is deduced from the string length.

◆ picosecond()

Picosecond picosecond ( ) const
inline

The current picosecond. Valid values are 0 through 999999999999.

Definition at line 282 of file Timestamp.h.

◆ second()

Second second ( ) const

The current second. Valid values are 0 through 59.

◆ toString() [1/2]

void toString ( std::string & str,
TimestampFormat::Enum = TimestampFormat::YYYYMMDDHHMMSSNsec ) const

Appends the timestamp text presentation in the requested format ("YYYYMMDD-HH:MM:SS.sssssssss" by default).

◆ toString() [2/2]

std::string toString ( TimestampFormat::Enum format = TimestampFormat::YYYYMMDDHHMMSSNsec) const
inline

Returns the timestamp text presentation in the requested format ("YYYYMMDD-HH:MM:SS.sssssssss" by default).

Definition at line 289 of file Timestamp.h.

◆ totalSeconds()

TotalSeconds totalSeconds ( ) const
inline

The total number of seconds since Jan 1, 0001, 00:00:00.

Definition at line 254 of file Timestamp.h.

◆ toUnixNanosecondTimestamp()

TotalNanoseconds toUnixNanosecondTimestamp ( ) const

Returns the nanosecond timestamp since the Unix epoch.

◆ utc()

Timestamp utc ( )
static

Returns the current UTC time.

Note
The timestamp resolution depends on capabilities of an operating system.

◆ year()

Year year ( ) const

The current year.
