| 14 | // Here, we support the W3C profile of ISO 8601 with the following | |
| 15 | // restrictions: | |
| 16 | // - Subsecond resolution is supported to nanosecond | |
| 17 | // granularity. Any number of digits between 1 and 9 may be | |
| 18 | // specified after the decimal point. | |
| 19 | // - All times must be UTC. | |
| 20 | // - All times must be representable as a sixty-four bit count of | |
| 21 | // nanoseconds since the epoch. | |
| 22 | // - Partial times are handled thus: | |
| 23 | // * If there are no subseconds, they are assumed to be zero. | |
| 24 | // * If there are no seconds, they are assumed to be zero. | |
| 25 | // * If there are no minutes, they are assumed to be zero. | |
| 26 | // * If there is no time, it is assumed to midnight. | |
| 27 | // * If there is no day, it is assumed to be the first. | |
| 28 | // * If there is no month, it is assumed to be January. | |
| 29 | // | |
| 30 | // If a date is invalid, boost::none is returned. | |
