Unable to delay-load azure-core because of SystemClockEpoch

[bellycat007]

We build the source and share the dll in our service. We are trying to delay load azure-core, but we got exception:

LINK : fatal error LNK1194: cannot delay-load 'azure-core.dll' due to import of data symbol '"
__declspec(dllimport)
private: static class Azure::DateTime const Azure::DateTime::SystemClockEpoch" (_imp?SystemClockEpoch@
DateTime@Azure@@0V12@B)';

We check the code and find this could be hide inside cpp file, then we can delay load it.

AZ_CORE_DLLEXPORT static DateTime const SystemClockEpoch;

/**

• @brief Construct an instance of %DateTime from std::chrono::system_clock::time_point.
• @param systemTime A value of std::chrono::system_clock::time_point.

*/
DateTime(std::chrono::system_clock::time_point const& systemTime)
: DateTime(
SystemClockEpoch + std::chrono::duration_cast(systemTime.time_since_epoch()))
{
}
