 #### Can you use more than one HomeSpan device on the same HomeKit network?
 
-* Yes, multiple ESP32's, each running a separate copy of HomeSpan, can be used on the same HomeKit network, provided that each device has a unique *Device ID*, a unique *Host Name*, and a unique *Display Name*.  Normally, the *Device ID* is randomly-generated by HomeSpan at start-up and will therefore automatically be unique across multiple devices.  Also, unless you override the suffix of the default *Host Name*, it will also be unique across multiple devices since HomeSpan uses the *Device ID* as the suffix of the *Host Name*.  The only thing you need to ensure is that you assign a different *Display Name* to each of your devices.  See the [HomeSpan API Reference](https://github.com/HomeSpan/HomeSpan/blob/master/docs/Reference.md) for details on how to do this.

 #### Will HomeSpan work on an ESP8266 device?
 
-* No, HomeSpan is coded specifically for the ESP32 and will not operate on an ESP8266 device, though an ESP8266 can be used as a remote [SpanPoint ESP-NOW](../docs/NOW.md) Device.

 #### Does HomeSpan support Television Services?
 
-* Yes.  Though undocumented by Apple and not officially part of HAP-R2, HomeSpan supports HomeKit Television controls.  See [Television Services](../docs/TVServices.md) for details.

 #### Can you add *custom* Services and Characteristics to HomeSpan?
 
-* Yes, HomeSpan includes two easy-to-use macros to define your own custom Services and custom Characteristics beyond those specified in HAP-R2.  See the [HomeSpan API Reference](https://github.com/HomeSpan/HomeSpan/blob/master/docs/Reference.md) for details and examples demonstrating how to do this.  Note that any new Characteristics you create will be *completely ignored* by the Home App.  Similarly, any new Services you create will be shown in the Home App on a tile labeled "Not Supported".  Apple ***does not*** provide any mechanism to extend the functionality of the Home App itself.  However, the place where custom Services and Characteristics can be used is in third-party applications designed for these extra features.  For example, the *Eve for HomeKit* App properly handles all the Services and Characteristics defined in HAP-R2, *plus* a variety of additional Services and Characteristics designed explictly for use with Eve products.  If you know the UUID codes for these extra Services and Characteristics you can add them to HomeKit and use them within the Eve App just as if they were HAP-R2 Services and Characteristics.

 #### Why does the Home App indicate the Doorbell Service is unsupported?
 
-* Though not documented in HAP-R2, it appears that the Doorbell Service is designed to be used in conjunction with another service, such as the Lock Mechanism.  If you add in a second service, the Home App will show the appropriate Tile (such as a Lock) with the Doorbell being the second service.  However, you can still use the Doorbell Service on a standalone basis --- even though the Home App says it is unsupported, a button press on the device will properly trigger a chime on your Home Pods as expected.

+#### How can I read the current date and time from within my sketch?
+
+* HomeSpan can automatically acquire the current date and time for your local timezone when you enable the HomeSpan Web Log using `homeSpan.enableWebLog()`. Note this command can be used to set the date and time even without enabling the Web Log itself (see the [HomeSpan API Reference](Reference.md) for details on how to do this).  Once the date and time has been acquired, you can use the built-in Arduino-ESP32 `getLocalTime(struct tm *info)` command whenever needed to populate *info* with the current date and time.  Note *info* is in [standard Unix](https://man7.org/linux/man-pages/man0/time.h.0p.html) `struct tm` format which is easily parsed as follows:
+
+```C++
+struct tm myTime;        // create a tm structure
+getLocalTime(&myTime);   // populate the tm structure with current date and time
+
+// print the individual elements of the tm structure (see standard Unix tm structure for details)
+
+Serial.printf("Current Date = %02d/%02d/%04d\n", myTime.tm_mon+1, myTime.tm_mday, myTime.tm_year+1900);
+Serial.printf("Current Time = %02d:%02d:%02d\n", myTime.tm_hour, myTime.tm_min, myTime.tm_sec);
+```
