| uint64_t | get_logical_time_ticks_ (int64_t uptime_ticks) |
| uint64_t | convert_uptime_ticks_to_est_master_ticks (int64_t uptime_ticks) |
| uint64_t | get_logical_time_us (void) |
| Get the logical time us value. This is the corrected us value after synchronisation. This represents the unix epoch timestamp in us of the overall mesh network. Basically, it converts logical ticks into us. | |
| uint64_t | get_logical_time_ticks () |
| Get the logical time ticks value. This is the corrected ticks value after synchronisation. This represents the unix epoch timestamp in ticks of the overall mesh network. | |
| void | apply_timer_sync (double new_slope, double new_offset) |
| Apply the synchronisation parameters. Once the LR is made, The result of it gives a drift value (slope) and the difference between itself and the reference (offset). This method permits to set these parameters in order to have the proper correction when getting timestamps values. | |
| void | set_new_epoch_unix_ref (uint64_t epoch_ref_us) |
| Set the new epoch unix ref value. Before the authority node starts a new network synchronisation, it should update the epoch reference. | |
| uint64_t | ticks_to_us_unix_time (uint64_t logical_tick) |
| uint64_t | get_current_unix_time_us (void) |
| Gets the current synchronized UNIX time. | |
| int64_t | get_uptime_ticks_with_epoch () |
| Get the uptime ticks with epoch value. This method concerns only the authority Role. This method will return the unix epoch timestamp based on the elapsed time (uptime - ref) and add the overall reference. | |
| double | get_current_slope_ticks () |
| Get the current slope ticks value. | |
| double | get_current_offset_ticks () |
| Get the current offset ticks value. | |
| uint64_t | uncompress_time (uint32_t compress_32bit_timestamp) |
| Convert a uint32_t timestamps into a uint64_t values. This should be used in the sink node. In the Mesh network, pakcet payload is limited. Therefore only uint32_t timestamp can be used. When the sink received this kind of value, it can reconstruct the correct timestamps value. | |

◆ apply_timer_sync()
| void apply_timer_sync | ( | double | slope_timer, |
