``` cpp

template<class charT, class traits, class Rep, class Period>
|
| 5 |
+
basic_ostream<charT, traits>&
|
| 6 |
+
operator<<(basic_ostream<charT, traits>& os, const duration<Rep, Period>& d);
|
| 7 |
+
```
|
| 8 |
+
|
| 9 |
+
*Effects:* Inserts the duration `d` onto the stream `os` as if it were
|
| 10 |
+
implemented as follows:
|
| 11 |
+
|
| 12 |
+
``` cpp
|
| 13 |
+
basic_ostringstream<charT, traits> s;
|
| 14 |
+
s.flags(os.flags());
|
| 15 |
+
s.imbue(os.getloc());
|
| 16 |
+
s.precision(os.precision());
|
| 17 |
+
s << d.count() << units-suffix;
|
| 18 |
+
return os << s.str();
|
| 19 |
+
```
|
| 20 |
+
|
| 21 |
+
where *`units-suffix`* depends on the type `Period::type` as follows:
|
| 22 |
+
|
| 23 |
+
- If `Period::type` is `atto`, *`units-suffix`* is `"as"`.
|
| 24 |
+
- Otherwise, if `Period::type` is `femto`, *`units-suffix`* is `"fs"`.
|
| 25 |
+
- Otherwise, if `Period::type` is `pico`, *`units-suffix`* is `"ps"`.
|
| 26 |
+
- Otherwise, if `Period::type` is `nano`, *`units-suffix`* is `"ns"`.
|
| 27 |
+
- Otherwise, if `Period::type` is `micro`, it is
|
| 28 |
+
*implementation-defined* whether *`units-suffix`* is `"`\textmu`s"`
|
| 29 |
+
(`"\u00b5\u0073"`) or `"us"`.
|
| 30 |
+
- Otherwise, if `Period::type` is `milli`, *`units-suffix`* is `"ms"`.
|
| 31 |
+
- Otherwise, if `Period::type` is `centi`, *`units-suffix`* is `"cs"`.
|
| 32 |
+
- Otherwise, if `Period::type` is `deci`, *`units-suffix`* is `"ds"`.
|
| 33 |
+
- Otherwise, if `Period::type` is `ratio<1>`, *`units-suffix`* is `"s"`.
|
| 34 |
+
- Otherwise, if `Period::type` is `deca`, *`units-suffix`* is `"das"`.
|
| 35 |
+
- Otherwise, if `Period::type` is `hecto`, *`units-suffix`* is `"hs"`.
|
| 36 |
+
- Otherwise, if `Period::type` is `kilo`, *`units-suffix`* is `"ks"`.
|
| 37 |
+
- Otherwise, if `Period::type` is `mega`, *`units-suffix`* is `"Ms"`.
|
| 38 |
+
- Otherwise, if `Period::type` is `giga`, *`units-suffix`* is `"Gs"`.
|
| 39 |
+
- Otherwise, if `Period::type` is `tera`, *`units-suffix`* is `"Ts"`.
|
| 40 |
+
- Otherwise, if `Period::type` is `peta`, *`units-suffix`* is `"Ps"`.
|
| 41 |
+
- Otherwise, if `Period::type` is `exa`, *`units-suffix`* is `"Es"`.
|
| 42 |
+
- Otherwise, if `Period::type` is `ratio<60>`, *`units-suffix`* is
|
| 43 |
+
`"min"`.
|
| 44 |
+
- Otherwise, if `Period::type` is `ratio<3600>`, *`units-suffix`* is
|
| 45 |
+
`"h"`.
|
| 46 |
+
- Otherwise, if `Period::type` is `ratio<86400>`, *`units-suffix`* is
|
| 47 |
+
`"d"`.
|
| 48 |
+
- Otherwise, if `Period::type::den == 1`, *`units-suffix`* is
|
| 49 |
+
`"[`*`num`*`]s"`.
|
| 50 |
+
- Otherwise, *`units-suffix`* is `"[`*`num`*`/`*`den`*`]s"`.
|
| 51 |
+
|
| 52 |
+
In the list above, the use of *`num`* and *`den`* refer to the static
|
| 53 |
+
data members of `Period::type`, which are converted to arrays of `charT`
|
| 54 |
+
using a decimal conversion with no leading zeroes.
|
| 55 |
+
|
| 56 |
+
*Returns:* `os`.
|
| 57 |
+
|
| 58 |
+
``` cpp
|
| 59 |
+
template<class charT, class traits, class Rep, class Period, class Alloc = allocator<charT>>
|
| 60 |
+
basic_istream<charT, traits>&
|
| 61 |
+
from_stream(basic_istream<charT, traits>& is, const charT* fmt,
|
| 62 |
+
duration<Rep, Period>& d,
|
| 63 |
+
basic_string<charT, traits, Alloc>* abbrev = nullptr,
|
| 64 |
+
minutes* offset = nullptr);
|
| 65 |
+
```
|
| 66 |
+
|
| 67 |
+
*Effects:* Attempts to parse the input stream `is` into the duration `d`
|
| 68 |
+
using the format flags given in the NTCTS `fmt` as specified in
|
| 69 |
+
[[time.parse]]. If the parse parses everything specified by the parsing
|
| 70 |
+
format flags without error, and yet none of the flags impacts a
|
| 71 |
+
duration, `d` will be assigned a zero value. If `%Z` is used and
|
| 72 |
+
successfully parsed, that value will be assigned to `*abbrev` if
|
| 73 |
+
`abbrev` is non-null. If `%z` (or a modified variant) is used and
|
| 74 |
+
successfully parsed, that value will be assigned to `*offset` if
|
| 75 |
+
`offset` is non-null.
|
| 76 |
+
|
| 77 |
+
*Returns:* `is`.
