Print a UTC offset into a string.

Format of the string is "[info]+hh[:mm[:ss]]h"

Parameters

[out]	s	Address of a string buffer to be filled.
[in]	max_len	Size of the string buffer.
[in]	info	An optional info string to be prepended, may be NULL.
[in]	utc_offs	The UTC offset to be printed, in [s].

Returns: The number of characters written to the output buffer, except the terminating 0.
