# Function: formatTime()
|
|

|
|
|
|
Defined in: [index.ts:113](https://github.com/acamarata/solar-spa/blob/3c848806ab852464d76baf7e3fc0ca58f5e42fd9/src/index.ts#L113)
|
|
|
|
Purpose: Convert fractional hours to an HH:MM:SS string.
|
|

|
|
Outputs: "HH:MM:SS" string, or "N/A" for non-finite/negative inputs
|
|
Constraints: Non-finite and negative values occur during polar day/night;
|
|
