// This header file defines abstractions for computing with absolute points
// in time, durations of time, and formatting and parsing time within a given
// time zone. The following abstractions are defined:
//
// * `absl::Time` defines an absolute, specific instance in time
// * `absl::Duration` defines a signed, fixed-length span of time
// * `absl::TimeZone` defines geopolitical time zone regions (as collected
// within the IANA Time Zone database (https://www.iana.org/time-zones)).
//
//

// Example:
//
// absl::TimeZone nyc;
//
// // LoadTimeZone() may fail so it's always better to check for success.
2017-09-19 22:54:40 +02:00
// if (!absl::LoadTimeZone("America/New_York", &nyc)) {

//
// // My flight leaves NYC on Jan 2, 2017 at 03:04:05
// absl::Time takeoff = absl::FromDateTime(2017, 1, 2, 3, 4, 5, nyc);
// absl::Duration flight_duration = absl::Hours(21) + absl::Minutes(35);
// absl::Time landing = takeoff + flight_duration;
//
// absl::TimeZone syd;

This is a forward-compatible implementation of std::from_chars from C++17. This provides exact "round_to_nearest" conversions, and has some nice properties: * Works with string_view (it can convert numbers from non-NUL-terminated buffers) * Never allocates memory * Faster than the standard library strtod() in our toolchain * Uses integer math in its calculations, so is unaffected by floating point environment * Unaffected by C locale Also change SimpleAtod/SimpleAtoi to use this new API under the hood.

// Duration
//
// The `absl::Duration` class represents a signed, fixed-length span of time.
// A `Duration` is generated using a unit-specific factory function, or is
// the result of subtracting one `absl::Time` from another. Durations behave
// like unit-safe integers and they support all the natural integer-like
// arithmetic operations. Arithmetic overflows and saturates at +/- infinity.
// `Duration` should be passed by value rather than const reference.
//
// Factory functions `Nanoseconds()`, `Microseconds()`, `Milliseconds()`,
// `Seconds()`, `Minutes()`, `Hours()` and `InfiniteDuration()` allow for
// creation of constexpr `Duration` values
//
// Examples:
//
// constexpr absl::Duration ten_ns = absl::Nanoseconds(10);
// constexpr absl::Duration min = absl::Minutes(1);
// constexpr absl::Duration hour = absl::Hours(1);
// absl::Duration dur = 60 * min; // dur == hour
// absl::Duration half_sec = absl::Milliseconds(500);
// absl::Duration quarter_sec = 0.25 * absl::Seconds(1);
//
// `Duration` values can be easily converted to an integral number of units
// using the division operator.
//
// Example:
//
// constexpr absl::Duration dur = absl::Milliseconds(1500);
// int64_t ns = dur / absl::Nanoseconds(1); // ns == 1500000000
// int64_t ms = dur / absl::Milliseconds(1); // ms == 1500
// int64_t sec = dur / absl::Seconds(1); // sec == 1 (subseconds truncated)
// int64_t min = dur / absl::Minutes(1); // min == 0
//
// See the `IDivDuration()` and `FDivDuration()` functions below for details on
// how to access the fractional parts of the quotient.
//
// Alternatively, conversions can be performed using helpers such as
// `ToInt64Microseconds()` and `ToDoubleSeconds()`.

// absl::Duration a = absl::Trunc(d, absl::Microseconds(1)); // 123456us

// Floor()
//
// Floors a duration using the passed duration unit to its largest value not
// greater than the duration.
//
// Example:
//
// absl::Duration d = absl::Nanoseconds(123456789);
// absl::Duration b = absl::Floor(d, absl::Microseconds(1)); // 123456us
Duration Floor(Duration d, Duration unit);
// Ceil()
//
// Returns the ceiling of a duration using the passed duration unit to its
// smallest value not less than the duration.
//
// Example:
//
// absl::Duration d = absl::Nanoseconds(123456789);
// absl::Duration c = absl::Ceil(d, absl::Microseconds(1)); // 123457us

// Time
//
// An `absl::Time` represents a specific instant in time. Arithmetic operators
// are provided for naturally expressing time calculations. Instances are
// created using `absl::Now()` and the `absl::From*()` factory functions that
// accept the gamut of other time representations. Formatting and parsing
// functions are provided for conversion to and from strings. `absl::Time`
// should be passed by value rather than const reference.
//
// `absl::Time` assumes there are 60 seconds in a minute, which means the
// underlying time scales must be "smeared" to eliminate leap seconds.
// See https://developers.google.com/time/smear.
2017-09-19 22:54:40 +02:00
//
// Even though `absl::Time` supports a wide range of timestamps, exercise
// caution when using values in the distant past. `absl::Time` uses the
// Proleptic Gregorian calendar, which extends the Gregorian calendar backward
// to dates before its introduction in 1582.
// See https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar
// for more information. Use the ICU calendar classes to convert a date in
// some other calendar (http://userguide.icu-project.org/datetime/calendar).
//
// Similarly, standardized time zones are a reasonably recent innovation, with
// the Greenwich prime meridian being established in 1884. The TZ database
// itself does not profess accurate offsets for timestamps prior to 1970. The
// breakdown of future timestamps is subject to the whim of regional
// governments.
//
// The `absl::Time` class represents an instant in time as a count of clock
// ticks of some granularity (resolution) from some starting point (epoch).
//
//
// `absl::Time` uses a resolution that is high enough to avoid loss in
// precision, and a range that is wide enough to avoid overflow, when
// converting between tick counts in most Google time scales (i.e., precision
// of at least one nanosecond, and range +/-100 billion years). Conversions
// between the time scales are performed by truncating (towards negative
// infinity) to the nearest representable point.
//
// Examples:
//
// absl::Time t1 = ...;
// absl::Time t2 = t1 + absl::Minutes(2);
// absl::Duration d = t2 - t1; // == absl::Minutes(2)
// absl::Time::Breakdown bd = t1.In(absl::LocalTimeZone());
//
class Time {
public:
// Value semantics.
// Returns the Unix epoch. However, those reading your code may not know
// or expect the Unix epoch as the default value, so make your code more
// readable by explicitly initializing all instances before use.
//
// Example:
// absl::Time t = absl::UnixEpoch();
// absl::Time t = absl::Now();
// absl::Time t = absl::TimeFromTimeval(tv);
// absl::Time t = absl::InfinitePast();
constexpr Time() {}

// TimeConversion
//
// An `absl::TimeConversion` represents the conversion of year, month, day,
// hour, minute, and second values (i.e., a civil time), in a particular
// `absl::TimeZone`, to a time instant (an absolute time), as returned by
// `absl::ConvertDateTime()`. (Subseconds must be handled separately.)
//
// It is possible, though, for a caller to try to convert values that
// do not represent an actual or unique instant in time (due to a shift
// in UTC offset in the `absl::TimeZone`, which results in a discontinuity in
// the civil-time components). For example, a daylight-saving-time
// transition skips or repeats civil times---in the United States, March
// 13, 2011 02:15 never occurred, while November 6, 2011 01:15 occurred
// twice---so requests for such times are not well-defined.
//
// To account for these possibilities, `absl::TimeConversion` is richer
// than just a single `absl::Time`. When the civil time is skipped or
// repeated, `absl::ConvertDateTime()` returns times calculated using the
// pre-transition and post-transition UTC offsets, plus the transition
// time itself.
//
// Examples:
//
// absl::TimeZone lax;
// if (!absl::LoadTimeZone("America/Los_Angeles", &lax)) {
// // handle error case
// }

// weekday (%a or %A), while parsed for syntactic validity, are ignored
// in the conversion.
//
// Date and time fields that are out-of-range will be treated as errors
// rather than normalizing them like `absl::FromDateTime()` does. For example,
// it is an error to parse the date "Oct 32, 2013" because 32 is out of range.
//
// A leap second of ":60" is normalized to ":00" of the following minute
// with fractional seconds discarded. The following table shows how the

//
// "59.x" -> 59.x // exact
// "60.x" -> 00.0 // normalized
// "00.x" -> 00.x // exact
//
// Errors are indicated by returning false and assigning an error message
// to the "err" out param if it is non-null.
//
// Note: If the input string is exactly "infinite-future", the returned
2017-09-19 22:54:40 +02:00
// `absl::Time` will be `absl::InfiniteFuture()` and `true` will be returned.
