Add TW_QCOM_ATS_OFFSET flag to manually set time/date offset
Needed if no ats_ files are present on qcom device
Offset is the difference between the current time
and the time since_epoch
To calculate the offset in Android, the following expression
(from a root shell) can be used:
echo "$(( ($(date +%s) - $(cat /sys/class/rtc/rtc0/since_epoch)) ))"
Add 3 zeros to the output and use that in the TW_QCOM_ATS_OFFSET
flag in your BoardConfig.mk
For example, if the result of the calculation is 1642433544,
use 1642433544000 as the offset
