| //! It seems odd that a system snapshot implementation would need a |
| //! ProcessReaderLinux, but some of the information reported about the |
| //! system depends on the process it’s being reported for. For example, |
| //! the architecture returned by GetCPUArchitecture() should be the |
| //! architecture of the process, which may be different than the native |
| //! architecture of the system: an x86_64 system can run both x86_64 and |
| //! 32-bit x86 processes. |
| //! \param[in] snapshot_time The time of the snapshot being taken. |
| //! \n\n |
| //! This parameter is necessary for TimeZone() to determine whether |
| //! daylight saving time was in effect at the time the snapshot was taken. |
| //! Otherwise, it would need to base its determination on the current |
| //! time, which may be different than the snapshot time for snapshots |
| //! generated around the daylight saving transition time. |
