class Time

GPS time container class.

Public Methods

Time(void)

Default constructor

Time(ulong_t sec, ulong_t nsec=0)

Constructor from seconds and nanoseconds.

Time(const Time& t)

Copy constructor

Time& operator=(const Time&)

Assignment operator

Time operator+=(const Interval& dt)

Add an Interval to a Time.

Interval operator -(const Time& dt) const

Subtract a Time rhs.

Time operator-=(const Interval& dt)

Subtract a constant rhs

bool operator!(void) const

Compare to zero

bool operator==(const Time& rhs) const

Compare times (equality)

bool operator!=(const Time& rhs) const

Compare times (inequality)

bool operator>=(const Time& rhs) const

Compare times (Greater or Equal)

bool operator<=(const Time& rhs) const

Compare times (Less or equal)

bool operator>(const Time& rhs) const

Compare times (Greater)

bool operator<(const Time& rhs) const

Compare times (Less than)

ulong_t getS(void) const

Number of nanoseconds.

ulong_t getN(void) const

Number of nanoseconds.

double totalS(void) const

GPS seconds since t0.

double totalNS(void) const

GPS nanoseconds since t0.

double fracS(void) const

Get the fractional seconds.

void setS(ulong_t s)

set seconds field.

void setN(ulong_t n)

Set nanosecon field.

Time(void)

A Time instance is created with no initialization performed.

Time(ulong_t sec, ulong_t nsec=0)

GPS time is constructed from seconds and nanoseconds. If the nanosecond field isn't specified, it is assumed to be zero.

Parameters:

sec - Number of GPS seconds since midnight, Jan 6, 1980.
nsec - Number of nanoseconds since last GPS second.

Time(const Time& t)

Copy constructor

Time& operator=(const Time&)

Assignment operator

Time operator+=(const Interval& dt)

Add an Interval to a Time.

Interval operator -(const Time& dt) const

Subtract a Time rhs.

Time operator-=(const Interval& dt)

Subtract a constant rhs

bool operator!(void) const

Compare to zero

bool operator==(const Time& rhs) const

Compare times (equality)

bool operator!=(const Time& rhs) const

Compare times (inequality)

bool operator>=(const Time& rhs) const

Compare times (Greater or Equal)

bool operator<=(const Time& rhs) const

Compare times (Less or equal)

bool operator>(const Time& rhs) const

Compare times (Greater)

bool operator<(const Time& rhs) const

Compare times (Less than)

ulong_t getS(void) const

Get the GPS second boundary.

Returns:

Then number of nanoseconds since a GPS secon.

ulong_t getN(void) const

Get the number of nanoseconds since a GPS second boundary.

Returns:

Then number of nanoseconds since a GPS secon.

double totalS(void) const

Get the GPS time in seconds since t0.

Returns:

The number of GPS seconds.

double totalNS(void) const

Get the GPS time in nanoseconds since t0.

Returns:

The number of GPS nanoseconds.

double fracS(void) const

Get the fraction of a second after an integer number of GPS seconds.

void setS(ulong_t s)

Set the number of seconds past the start of the second GPS epoch.

void setN(ulong_t n)

Set the number of nanoseconds offset from the seconds field.
