[Feature Request] Saving timestamp values

[tomoyuki28jp]

To implement this functionality, it may be necessary to transmit the 'transform' property. https://gist.github.com/mikelehen/6c8f67164f18b7b49135231f1cc0cf29

The Firestore API already includes the createTime and updateTime timestamp values by default, as far as I know this is already included in the library too:
API ref:
https://cloud.google.com/firestore/docs/reference/rest/v1/projects.databases.documents#get

Fireworkers:

fireworkers/src/fields.ts

Line 93 in 00de6db

...timestamps,

If I understand correctly,

• The library only allows the metadata createTime/updateTime to be used, but we can't sort or filter on those columns Sort/filter on createTime/updateTime googleapis/google-cloud-node#7491
• We cannot use this library to store timestamp type data

I will probably not be using this library, so feel free to close this issue if you don't need the feature!
