10.1.5. Real-Time clock function
• This data logger module incorporates an accurate battery-backed real-time clock to display the date and
time of day.
• It compensates for leap years.
• It does not automatically compensate for daylight saving in summer and winter.
• This clock is used to timestamp data within the data logger files. It is also used to date and time stamp
the actual file.
• Note:
The date and time stamp of the file is the time the file was last written to (not the time when the file was
first created).
• The battery is designed for a service life of around 10 years.
