TDU Error Log Date and Time Information
When the GE T2100 Treadmill is manufactured, or whenever the event
log (flash memory) is erased, the system date and time (SDT) is set to
January 1, 2050, 0:00:00 and is then stored into the flash memory. When
power is applied to the GE T2100 Treadmill, the SDT is set to the saved
SDT in the flash memory. While power is applied, the system updates
the SDT every second. When the power is lost, the updated SDT is saved
back to the flash memory. Therefore, the SDT is also the total power-up
date and time, which is always relative to the initial date and time of
January 1, 2050, 0:00:00.
The SDT is used when logging events in two different modes, the Default
Mode and the Host Synchronized Mode.
Default Mode
When the GE T2100 Treadmill power switch is turned on, the GE T2100
Treadmill will always initialize in the Default Mode. When an event is
logged while the system is in this mode, the event will be date and time
stamped with the total power-up date and time.
