Using Date from propertyprobe.h in GStreamer 1.0

To use the date declared in 'propertyprobe.h' in GStreamer 1.0, follow these steps:

Include the header file: Add the following line at the top of your GStreamer 1.0 code file:
```
#include 'propertyprobe.h'
```
Declare a variable: Declare a variable of the appropriate data type to store the date. For instance, if the date is a string, use:
```
char* date;
```
Initialize the variable: Assign the value from 'propertyprobe.h' to the variable. This depends on how the date is defined. If it's a macro, directly assign it:
```
date = PROPERTY_PROBE_DATE;
```
Use the variable: Now you can utilize the 'date' variable in your GStreamer 1.0 code. For example, to print it:
```
g_print('Date: %s\n', date);
```

Remember to have 'propertyprobe.h' accessible in your project and ensure necessary dependencies and libraries are linked during compilation.
