Hello @SWAPAC

Please note that RTC time and system time are different. If you set RTC time it won’t affect system time and vice versa. However, they are synchronized.  
you can refer to the dedicated article on [legato.io](http://legato.io) explaining the difference:  
[Set User Timebase - Legato Docs](https://docs.legato.io/latest/howToSetUserTimebase.html)

you can also refer to the following post which gives an example of command line to set the system time using NTP service and then set RTC based on the system time:

> Hi subrahmaniam, Per understanding, if you want to do all in your application, you need to develop according to NTP protocol (i.e. RFC-1305, RFC-5905). In latest Legato release, le\_data\_GetDate() and le\_data\_GetTime() is introduced for NTP support to ease development. [https://docs.legato.io/latest/c\_le\_data.html#c\_le\_data\_time](https://docs.legato.io/latest/c_le_data.html#c_le_data_time) But for your case using 16.07, I think the easiest way is to use Linux script or call those Linux tool in your app. You may refer to my test below: root@swi-mdm9x15…

Hope it clarifies the situaiton
