moment.utc is not a function

[geekeren]

I use moment.utc to format time from UTC string, according to https://hexo.io/zh-cn/docs/helpers.html#moment, so I search momentjs and moment-timezone， so used utc() function to parse it, but failed with following error:

    28|                             } %>
    29|                             <span class="gt-comment-date">
 >> 30|                                 <%= moment.utc(comment.comment_date_gmt).format('YYYY-MM-DD hh:mm') %>
    31|                             </span>

moment object can not be use inside template directly.

Only a moment() method is available. Try using moment(date).utc() or sorts of things.
