Configuration file types

[Eric.VanAlst@…]

In SDR-14 section 5.1.4.2.1 mentions valid time types are UTC, UT1, TAI, and TT
but there is no corresponding type defined in psMetadataType in section 5.1.2.
There is also a comment that time type values be in ISO8601 format, but there
is no time type specified.

UTC, UT1, TAI, and TT are psTimeTypes and as such are only relevant to a psTime
object. A psTime objects is what would be stored in a psMetadataItem. I hope
that answers your question. However, I did notice that there was no meta flag
for psTimes in psMetadataType.

The following change to the SDRS has been made:

UTC, UT1, TAI, and TT can all be expressed as an ISO8601 formatted string. I've
changed the psTimeFromISO() prototype so the time system of the resulting psTime
object can be specified.
