Fixed incorrect Spanish translation for "time" string in clock widget

[victor-marino]

Just fixing a minor error with the translation of the "Time" word.

It had been originally translated as tiempo, which is the generic word for time in Spanish (e.g.: "It's been a long time").

However, in this context it obviously refers to the time of day in the clock (e.g.: "What time is it?"), which is translated as hora in Spanish.
