Before you can set the time you will need to enable the firmware updater. To do this, uncomment the "ENABLE_UPDATER" line in the config and flash the firmware. You can confirm this worked by looking at the console log in the Arduino IDE. When the OSCR is first connected/powered on it will immediately send its hardware version, firmware version, and enabled features over serial. You can verify this further by typing `VERCHK` into the input and pressing enter to get this information.
To check the current time you can use the command `GETTIME` which will cause the OSCR to send the current date/time over serial. To set the time, you will need to know the time value as a UNIX epoch/offset. You can use an [online tool)(https://www.epochconverter.com/) to help you with that. Make sure the timezone is set to UTC unless you are on Linux and entering a local time. Pad it by a few seconds to give you time to type the command. The command is `SETTIME <timestamp>`, such as `SETTIME 1689468590`. This will immediately set the time and return the resulting human-readable date and time. You can do this a few times until the clock is as accurate as you need it.
