Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xd::time_span.

Note that, because of the loss of precision of the Double data type, this conversion can cause an xtd::overflow_exception for values that are near to but still in the range of either xd::time_span::min_value or xd::time_span::max_value. For example, this causes an xtd:overflow_exception in the following attempt to instantiate a xd::time_span object.

// The following throws an overflow_exception at runtime
auto max_span = time_span::from_days(time_span::max_value.total_days());

xtd::argument_exception	value is equal to xtd::double_object::NaN.

Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xtd::time_span.

An object that represents value.

from_nanoseconds() [2/2]

static time_span xtd::time_span::from_nanoseconds ( std::chrono::nanoseconds value )

static

Returns a xtd::time_span that represents a specified number of nanoseconds.

Parameters

value

A number of nanoseconds.

Returns

An object that represents value.

from_seconds() [1/2]

static time_span xtd::time_span::from_seconds ( double value )

static

Returns a xtd::time_spam that represents a specified number of seconds, where the specification is accurate to the nearest millisecond.

Parameters

value

A number of minutes, accurate to the nearest second.

Returns

An object that represents value.

Exceptions

xtd::overflow_exception	value is less than xtd::time_span::min_value or greater than xtd::time_span::max_value. -or- value is xtd::double_object::positive_infinity. -or- value is xtd::double_object::negative_infinity.
xtd::argument_exception	value is equal to xtd::double_object::NaN.

Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xtd::time_span. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this conversion can generate an xtd::overflow_exception for values that are near to but still in the range of either xtd::time_span::min_value or xtd::time_span::max_value. For example, this causes an xtd::overflow_exception in the following attempt to instantiate a xtd::time_span object.

// The following throws an overflow_exception at runtime
auto max_span = time_span::from_seconds(time_span::max_value::total_seconds);

from_seconds() [2/2]

static time_span xtd::time_span::from_seconds ( std::chrono::seconds value )

static

Returns a xtd::time_span that represents a specified number of seconds.

Parameters

value

A number of seconds.

Returns

An object that represents value.

from_ticks() [1/2]

static time_span xtd::time_span::from_ticks ( int64 value )

static

Returns a xtd::time_spam that represents a specified time, where the specification is in units of ticks.

Parameters

value

A number of ticks that represent a time.

Returns

An object that represents value.

from_ticks() [2/2]

static time_span xtd::time_span::from_ticks ( xtd::ticks value )

static

Returns a xtd::time_span that represents a specified number of ticks.

Parameters

value

A number of ticks.

Returns

An object that represents value.

Remarks

This is a convenience method with the same behavior as the xtd::time_spam.xtd::time_spam (int64) constructor. A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond.

try_parse()

static bool xtd::time_span::try_parse ( const string & value, time_span & result )

static

Converts the string representation of a time interval to its xtd::time_span equivalent and returns a value that indicates whether the conversion succeeded.

Parameters

value	A string that specifies the time interval to convert.
result	When this method returns, contains an object that represents the time interval specified by value, or xtd::time_span::zero if the conversion failed.

Returns

true if s was converted successfully; otherwise, false. This operation returns false if the value parameter is empty (""), has an invalid format, represents a time interval that is less than xtd::time_span::min_value or greater than xtd::time_span::max_value, or has at least one days, hours, minutes, or seconds component outside its valid range.

Member Data Documentation

max_value

const time_span xtd::time_span::max_value

static

Represents the maximum xtd::time_span value. This field is read-only.

Remarks

The value of this field is equivalent to xtd::int64_object::max_value ticks. The string representation of this value is positive 10675199.02:48:05.4775807, or slightly more than 10,675,199 days.

min_value

const time_span xtd::time_span::min_value

static

Represents the minimum xtd::time_span value. This field is read-only.

Remarks

The value of this field is equivalent to xtd::int64_object::min_value ticks. The string representation of this value is negative 10675199.02:48:05.4775808, or slightly more than negative 10,675,199 days.

nanoseconds_per_tick

int64 xtd::time_span::nanoseconds_per_tick

staticconstexpr

Represents the number of nanoseconds per tick. This field is constant.

Remarks

The value of this constant is 100.

ticks_per_microsecond

int64 xtd::time_span::ticks_per_microsecond

staticconstexpr

Represents the number of ticks in 1 microsecond. This field is constant.

Remarks

The value of this constant is 10.

ticks_per_millisecond

int64 xtd::time_span::ticks_per_millisecond

staticconstexpr

Represents the number of ticks in 1 millisecond. This field is constant.

Remarks

The value of this constant is 10 thousand; that is, 10,000.

ticks_per_second

int64 xtd::time_span::ticks_per_second

staticconstexpr

Represents the number of ticks in 1 second.

Remarks

he value of this constant is 10 million; that is, 10'000'000.

ticks_per_minute

int64 xtd::time_span::ticks_per_minute

staticconstexpr

Represents the number of ticks in 1 minute. This field is constant.

Remarks

The value of this constant is 600 million; that is, 600'000'000.

ticks_per_hour

int64 xtd::time_span::ticks_per_hour

staticconstexpr

Represents the number of ticks in 1 hour. This field is constant.

Remarks

The value of this constant is 36 billion; that is, 36'000'000'000.

ticks_per_day

int64 xtd::time_span::ticks_per_day

staticconstexpr

Represents the number of ticks in 1 day. This field is constant.

Remarks

The value of this constant is 864 billion; that is, 864'000'000'000.

zero

const time_span xtd::time_span::zero

static

Represents the zero xtd::time_span value. This field is read-only.

Remarks

Because the value of the Zero field is a xtd::time_span object that represents a zero time value, you can compare it with other xtd::time_span objects to determine whether the latter represent positive, non-zero, or negative time intervals. You can also use this field to initialize a xtd::time_span object to a zero time value.
