Parse an input string according to the provided format string into a Unix time, the number of seconds / milliseconds / microseconds / nanoseconds elapsed since January 1, 1970 UTC. Uses strftime()-like formatting options, with the same extensions as FormatTime(), but with the exceptions that %E#S is interpreted as %E*S, and %E#f as %E*f. %Ez and %E*z also accept the same inputs. %Y consumes as many numeric characters as it can, so the matching data should always be terminated with a non-numeric. %E4Y always consumes exactly four characters, including any sign. Unspecified fields are taken from the default date and time of ... "1970-01-01 00:00:00.0 +0000" For example, parsing a string of "15:45" (%H:%M) will return an Unix time that represents "1970-01-01 15:45:00.0 +0000". Note that ParseTime only heeds the fields year, month, day, hour, minute, (fractional) second, and UTC offset. Other fields, like weekday (%a or %A), while parsed for syntactic validity, are ignored in the conversion. Date and time fields that are out-of-range will be treated as errors rather than normalizing them like `absl::CivilSecond` does. For example, it is an error to parse the date "Oct 32, 2013" because 32 is out of range. A leap second of ":60" is normalized to ":00" of the following minute with fractional seconds discarded. The following table shows how the given seconds and subseconds will be parsed: "59.x" -> 59.x // exact "60.x" -> 00.0 // normalized "00.x" -> 00.x // exact Args: time_string: The input time string to be parsed. time_format: The time format. output_unit: The output unit of the parsed unix time. Can only be SECOND, MILLISECOND, MICROSECOND, NANOSECOND. Returns: the number of seconds / milliseconds / microseconds / nanoseconds elapsed since January 1, 1970 UTC. Raises: ValueError: If `output_unit` is not a valid value, if parsing `time_string` according to `time_format` failed. z-parse_time is not yet implemented on Windows.)Ú IS_WINDOWSÚNotImplementedErrorÚ_parse_time_soÚopsZaddons_parse_time)rrr©r úS/home/dcms/DCMS/lib/python3.7/site-packages/tensorflow_addons/text/parse_time_op.pyÚ parse_times7r) Ú__doc__ÚplatformZ tensorflowÚtfZ'tensorflow_addons.utils.resource_loaderrÚsystemrr Z no_gradientÚstrZTensorrr r r r Ús
