Hi,
I am wondering whether U-Boot already has the functionality to retrieve the number of seconds since beginning of the 1970-01-01 epoch. I would like to use this value in a Hush script.
For a product I have the requirement to detect if the current booting happens within x seconds of the last boot. I already have access to the system’s RTC and can read it with U-Boot’s date command. This returns the current date and time in a nice human readable format. I am now looking for something which would return a timestamp in seconds. I could then fulfill the afore mentioned requirement by calculating the difference between two timestamps using Hush and the let command.
Alternative proposals how to fulfill the requirement within U-Boot are welcome, too. ☺
Best regards, Mark
