[Cost Management] FOCUS datasets do not include seconds in dates

[flanakin]

🐛 Problem

FOCUS date columns are formatted without seconds when they should include seconds.

Actual/Expected	Value
Actual	yyyy-MM-ddTHH:mmZ
Expected	yyyy-MM-ddTHH:mm:ssZ

This impacts the following columns:

• BillingPeriodStart/End
• ChargePeriodStart/End
• x_BillingExchangeRateDate
• x_ServicePeriodStart/End

👣 Repro steps

1. Export FOCUS cost details (any version)
2. Review any of the date columns
3. Note they are missing the seconds

🤔 Expected

All dates should be formatted with seconds (yyyy-MM-ddTHH:mm:ssZ).

ℹ️ Additional context

Wikipedia says that seconds are optional. We need to confirm with the actual ISO 8601 specification.

Regardless, we have received a report that not having seconds is breaking parsing in some database engines. Due to this, the Cost Management team is working on a fix.
