Do you have a specification for the DL750 realtime clock in terms of accuracy and drift ?

Do you have a specification for the DL750 realtime clock in terms of accuracy and drift ?
There is no specification for the realtime clock on DL750.
In the worst case, this clock drifts about 10 minute in one month if the clock is not corrected.
If you have ethernet, please consider using SNTP and update from a reliable SNTP server periodically.
