Bases: lsst.ts.MTMount.field_info.BaseFieldInfo

Date and time field.

The str representation is ISO-8601, with “T” between the date and time. For example: “2020-02-27T14:48:27.469”.

Parameters:

name : str

Name of field. Must be a valid Python identifier.

doc : str (optional)

Description of the field.

scale : str

One of “tai” or “utc”. Support for other values supported by astropy.time can easily be added, if needed. But Tekniker’s code only uses UTC and TAI.
