 a) Header Line
 First Line of a valid file has to contain header information. This has to be a comma-separated 
 list of the measures provided in the data lines. You do not need to provide all possible measures,
 but at least "ts" and "weightkg".
 
-The mandatory measures are:
+As mandatory field you need time/date of the measures. There are 2 options:
 - "ts" 			- Unix timestamp (in seconds) since Epoch. The value can be calcuated in XLS - just Google how-to.
+OR
+- "date"		- ISO8601 formatted Date/Time String

 - "weightkg" 	- Athlete weight in kilograms
