Due to YAML formatting, there's always a second push to index

[amis92]

The issue it in YAML conversion of DateTime(Offset) first being serialized with the Z timezone indication when taken directly from JSON, and then after reading from YAML and resaving it, serialized as timezone offset +0000.

The easiest solution right now would be round-tripping the yaml on save:

• save yaml
• read yaml again and re-save
