That is, the 119 * format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z" 120 * where {year} is always expressed using four digits while {month}, {day}, 121 * {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional 122 * seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution), 123 * are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone 124 * is required. A proto3 JSON serializer should always use UTC (as indicated by 125 * "Z") when printing the Timestamp type and a proto3 JSON parser should be 126 * able to accept both UTC and other timezones (as indicated by an offset). 127 * 128 * For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past 129 * 01:30 UTC on January 15, 2017. 130 * 131 * In JavaScript, one can convert a Date object to this format using the 132 * standard 133 * [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) 134 * method.
