Moreover, it is used to configure several parameters of RTC. SYNOPSIS dpyrtctool [-h/ --help] dpyrtctool [-tv / --toolversion] dpyrtctool [-sst/ --setsynctime] <time> dpyrtctool [-sdt/ --setdifftime] <time> dpyrtctool [-gcv / --getconfvalues] dpyrtctool [-gt / --gettime] dpyrtctool [-rs / --remsrc] <name> dpyrtctool [-as / --addsrc] <name> <type> <priority> <uri> <local_time> dpyrtctool [-gs / --getsources] OPTIONS -h / --help : Print help command information. -tv / --toolversion : Print tool version. -sst / --setsynctime <time> : Set synchronism time period in seconds. (range: 10 - 300) -sdt / --setdifftime <time> : Set maximum time in seconds allowed to RTC to be drifted from UTC valid time. (range: 1 - 30) Description: <time> : Time value provided in seconds. -gcv / --getconfvalues : Get RTC configuration parameters. -gt / --gettime : Get current RTC date and time -rs / --remsrc : Remove Date Source by name. Description: <name> : Name of the source. -as / --addsrc <name> <type> <priority> <uri> <local_time>: Add Date Source. Description: <name> : Name of the source. <type> : Type of date source. Possible values are: GNSS (Gnss device) MODEM (Modem device) SNTP (SNTP Server) FILE (File containing a line with date time info in ISO 8601:2000 standard date format [%FT%TZ] Check SEE ALSO instructions below) <priority> : Priority of date source. Possible values are positive integer value. (range: 1 - 100) NOTE : Lower number indicates higher priority. <uri> : URL/IP address or file absolute path where date source is located (127.0.0.1 for localhost). <local_time> : Indicates if date and time are local or UTC. Possible values are: true : local time false : UTC time -gs / --getsources : Get RTC sources.
