Overview

A Timestamp represents a point in time independent of any time zone or calendar, represented as seconds and fractions of seconds at nanosecond resolution in UTC Epoch time. It is encoded using the Proleptic Gregorian Calendar which extends the Gregorian calendar backwards to year one. It is encoded assuming all minutes are 60 seconds long, i.e. leap seconds are " smeared" so that no leap second table is needed for interpretation. Range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By restricting to that range, we ensure that we can convert to and from RFC 3339 date strings. See https://www.ietf.org/rfc/rfc3339.txt.

Examples

Example 1: Compute Timestamp from POSIX time(). Timestamp timestamp; timestamp.set_seconds(time(NULL)); timestamp.set_nanos(0); Example 2: Compute Timestamp from POSIX gettimeofday(). struct timeval tv; gettimeofday(&tv, NULL); Timestamp timestamp; timestamp.set_seconds(tv.tv_sec); timestamp.set_nanos(tv. tv_usec * 1000); Example 3: Compute Timestamp from Win32 GetSystemTimeAsFileTime(). FILETIME ft; GetSystemTimeAsFileTime(&ft); UINT64 ticks = (((UINT64)ft. dwHighDateTime) << 32) | ft.dwLowDateTime; // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z. Timestamp timestamp; timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL)); timestamp.set_nanos((INT32) ((ticks % 10000000) * 100)); Example 4: Compute Timestamp from Java System.currentTimeMillis(). long millis = System.currentTimeMillis(); Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000) . setNanos((int) ((millis % 1000) * 1000000)).build(); Example 5: Compute Timestamp from current time in Python. timestamp = Timestamp() timestamp.GetCurrentTime()

JSON Mapping

In JSON format, the Timestamp type is encoded as a string in the RFC 3339 format. That is, the format is "year- month-dayThour:min:sec[.frac_sec]Z" where year is always expressed using four digits while month, day, hour, min, and sec are zero-padded to two digits each. The fractional seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution), are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone is required, though only UTC (as indicated by "Z") is presently supported. For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past 01:30 UTC on January 15, 2017. In JavaScript, one can convert a Date object to this format using the standard toISOString()`]( http://joda-time.sourceforge.net/ apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()) to obtain a formatter capable of generating timestamps in this format.

Constructor Details

#initialize(**args) ⇒ Timestamp

Returns a new instance of Timestamp

def initialize(**args)
   update!(**args)
end

Instance Attribute Details

#nanos ⇒ Fixnum

Non-negative fractions of a second at nanosecond resolution. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be from 0 to 999,999,999 inclusive. Corresponds to the JSON property nanos

Returns:

• (Fixnum)

def nanos
  @nanos
end

#seconds ⇒ Fixnum

Represents seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z inclusive. Corresponds to the JSON property seconds

Returns:

• (Fixnum)
