Current Time since epoch too big to send as rospy.Time?

edit

I created a server and client pair program. The client sends a request with a rospy.time object. I save the current time since epoch into seconds and nano seconds fields of the time object. When I send the object to the server with a serviceProxy object I get a serialization error saying something is too large. I am assuming it is the nano seconds field:

 genpy.message.SerializationError: <class 'struct.error'>: ''I' format requires 0 <= number <= 4294967295' when writing 'time_input: 
  secs: 1597463455
  nsecs: 1597463455981233686'

Based on the documentation secs/nsecs are signed 32-bit ints. Since nsecs is larger than a 32bit int can hold, is it just impossible to send the current time since epoch in a rospy.time object? Is there a way around this besides creating a completely new message type? I attached everything just in case.

Thanks!!

convertTime.srv file:

time time_input
---
string time_string
float32 time_secs

Client .py File:

#!/usr/bin/env python3
import rospy
import time
from practice.srv import convertTime, convertTimeRequest, convertTimeResponse

#Initiate node and serviceProxy
rospy.init_node('time_converter_client')
serviceProxy = rospy.ServiceProxy('convertTime',convertTime)
rospy.wait_for_service('convertTime')

#Create time object and fill with current time
timeObject = rospy.Time()
timeObject.nsecs = int(time.time_ns())
timeObject.secs = int(time.time())

#Send request and handle response
response = serviceProxy(convertTimeRequest(timeObject))
print("Server Response: ")
print(response)

Server.py File

#!/usr/bin/env python3
import rospy
import time
from practice.srv import convertTime, convertTimeRequest, convertTimeResponse

def convert(msg):
    #save the original seconds recieved in msg
    secs = msg.time_input.secs
    #convert seconds since epoch to a readable time
    string_time = time.ctime(secs)
    #return a convertTimeResponse object with its field data passed to it
    return convertTimeResponse(string_time,secs)


#Initiate node and Service
rospy.init_node('time_converter_service')
service = rospy.Service('convertTime',convertTime,convert)
rospy.spin()
