Update EventPropertiesDecorator to respect the value set by SetTimestamp

[kindbe]

EventPropertiesDecorator ignores any value specified in EventProperties::SetTimestamp and all records get the timestamp value set in BaseDecorator (PAL::getUtcSystemTimeinTicks()). This change updates EventPropertiesDecorator::decorate to set record.time to eventProperties.GetTimestamp() if it is non-zero.

Any test updates with this?

Any test updates with this?

We have some tests that simply validate the record timestamp. Maybe we can add a few lines / an extra test in that same test, that sets the timestamp 1 hour behind, and verify that it matches.

Drat, I missed Matt's comment prior to hitting the button. I had looked for EventPropertiesDecorator tests but didn't find any. @maxgolov if you can point me in the right direction, I can look at updating the record test(s).

@kindbe - something around here, and/or maybe a callback similar to that one:

cpp_client_telemetry/tests/functests/APITest.cpp

Line 681 in 477292d

EXPECT_EQ(record.time, int64_t(recordTimeTicks.ticks) );
