title: Another issue in Discord Bot Reminder command in discord.py
body: <p>recently I've made a discord bot reminder command and got an issue with it, but thanks to Nurqm's help I was able to fix it.
  However, I got another issue in the time setting, when I do <code>/reminder 5days Fix the server</code>, which is a reminder to remind me to fix the server after 5 days, I get a ValueError.</p>
  <p>This is my code:</p>
  <pre><code>@client.command(case_insensitive = True, aliases = [&quot;remind&quot;, &quot;remindme&quot;, &quot;remind_me&quot;])
  @commands.bot_has_permissions(attach_files = True, embed_links = True)
  async def reminder(ctx, time, *, reminder):
      print(time)
      print(reminder)
      user = ctx.message.author
      embed = discord.Embed(color=0x55a7f7, timestamp=datetime.utcnow())
      embed.set_footer(text=&quot;If you have any questions, suggestions or bug reports, please join our support Discord Server: link hidden&quot;, icon_url=f&quot;{client.user.avatar_url}&quot;)
      seconds = 0
      if reminder is None:
          embed.add_field(name='Warning', value='Please specify what do you want me to remind you about.') # Error message
      if time.lower().endswith(&quot;days&quot;):
          seconds += int(time[:-4]) * 60 * 60 * 24
          counter = f&quot;{seconds // 60 // 60 // 24} days&quot;
      if time.lower().endswith(&quot;h&quot;):
          seconds += int(time[:-1]) * 60 * 60
          counter = f&quot;{seconds // 60 // 60} hours&quot;
      elif time.lower().endswith(&quot;m&quot;):
          seconds += int(time[:-1]) * 60
          counter = f&quot;{seconds // 60} minutes&quot;
      elif time.lower().endswith(&quot;s&quot;):
          seconds += int(time[:-1])
          counter = f&quot;{seconds} seconds&quot;
      if seconds == 0:
          embed.add_field(name='Warning',
                          value='Please specify a proper duration, send reminder_help for more information.')
      elif seconds &lt; 300:
          embed.add_field(name='Warning',
                          value='You have specified a too short duration!\nMinimum duration is 5 minutes.')
      elif seconds &gt; 7776000:
          embed.add_field(name='Warning', value='You have specified a too long duration!\nMaximum duration is 90 days.')
      else:
          await ctx.send(f&quot;Alright, I will remind you about {reminder} in {counter}.&quot;)
          await asyncio.sleep(seconds)
          await ctx.send(f&quot;Hi, you asked me to remind you about {reminder} {counter} ago.&quot;)
          return
      await ctx.send(embed=embed)
  </code></pre>
  <p>The error is: <code>Command raised an exception: ValueError: invalid literal for int() with base 10: '5day'</code></p>
  <p>If anyone knows any information about how to deal with this error please inform me. Thanks in advance.</p>
