# realtime-sync
realtime synchronisation daemon for OpenOS
realtime-sync uses the Date: header in HTTP responses, using the Internet card, to ascertain the current real time in UTC, and updates the realtime library with this information.
## Usage
realtime-sync is implemented as an rc service, and as such, to start it one can use the usual rc commands:
rc realtime-sync start
rc realtime-sync stop
rc realtime-sync enable
rc realtime-sync disable
Additionally, realtime-sync includes
rc realtime-sync sync
to force a re-synchronisation.
## Configuration
realtime-sync includes a configuration file at */etc/realtime-sync.cfg*; as a Lua table. It contains the following fields:
- **url**: The URL to request to get the time. Pick one that returns UTC dates in the headers, or leave the default.
- **offset**: The timezone offset, in hours. For example, for AEDT, use 11.
- **frequency**: The time between automatic time synchronisations.
