sandbox: keep time offset when resetting
The UEFI Self Certification Test (SCT) checks the SetTime() service with the following steps: * set date * reset * check date matches To be compliant the sandbox should keep the offset to the host RTC during resets. The implementation uses the environment variable UBOOT_SB_TIME_OFFSET to persist the offset. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
