I am trying to find the power OFF duration of the Delkin SSD. If a SSD is Powered ON and Powered OFF and then Powered ON, Can I know the Power OFF duration? Is there any Smart data with which I can find or by looking into the data retention duration I can find?
Thanks for all the answers and especially XY problem. Update on my problem.
For my system I record data and time-stamp againest RTC. I dont have battery. If RTC resets the time goes back to epoch time until I reset it. So, my most recent data will have oldest time stamp. So, When I power-up is there any way I know from SSD for how long it was powered OFFsince last power ON? With this I can automatically set the time whenever power ON. Is there anything in SMART data which I can see that for how long my SSD was OFF or is there anything from P/E cycles I can calculate the age of SSD and determine an approximate current time and will be curious about its accuracy.
