Timestamp of last change (server time, converted to the configured time zone).
Each currency rate change event forces this property to change its value.

Date variable containing the server timestamp

The timestamp is converted to the timezone, previously configured by the user.

If no timezone configuration was made the timestamp is converted to UTC.

See the usage of CQGCurrencyRate properties in the CurrencyRatesChanged event's example section.
