That is, the 116 * format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z" 117 * where {year} is always expressed using four digits while {month}, {day}, 118 * {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional 119 * seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution), 120 * are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone 121 * is required. A proto3 JSON serializer should always use UTC (as indicated by 122 * "Z") when printing the Timestamp type and a proto3 JSON parser should be 123 * able to accept both UTC and other timezones (as indicated by an offset). 124 * 125 * For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past 126 * 01:30 UTC on January 15, 2017. 127 * 128 * In JavaScript, one can convert a Date object to this format using the 129 * standard 130 * [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) 131 * method. In Python, a standard `datetime.datetime` object can be converted 132 * to this format using 133 * [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with 134 * the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use 135 * the Joda Time's [`ISODateTimeFormat.dateTime()`]( 136 * http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D 137 * ) to obtain a formatter capable of generating timestamps in this format. 138 **/ 139 GPB_FINAL @interface GPBTimestamp : GPBMessage 140 141 /** 142 * Represents seconds of UTC time since Unix epoch 143 * 1970-01-01T00:00:00Z.
