Took it off my VIP Expire plugin, just removed some parts:

PHP Code:

#include <amxmodx>
#include <amxmisc>

#define PLUGIN "New Plug-In"
#define VERSION "1.0"
#define AUTHOR "author"

#define parseTime(%1)            parse_time(%1, "%m/%d/%Y %H:%M:%S")

const iYearSeconds =            31536000
const iMonthSeconds =             2629800
const DaySeconds =             86400
const HourSeconds =             3600
const MinuteSeconds =             60

public plugin_init() 
{
    register_plugin(PLUGIN, VERSION, AUTHOR)
    
    register_concmd("amx_display_time", "cmdDateCommand", ADMIN_KICK, "<date format> - example: 05/01/2025 18:00:00")
}

public cmdDateCommand(id, iLevel, iCid)
{
    if(!cmd_access(id, iLevel, iCid, 2))
        return PLUGIN_HANDLED
        
    new szTime[60]
    read_argv(1, szTime, charsmax(szTime))
    
    new szMessage[192], iTime = parseTime(szTime)
    formatTime(iTime, szMessage, charsmax(szMessage))
    console_print(id, "Time remaining: %s", szMessage)
    return PLUGIN_HANDLED
}

formatTime(iTime, szMessage[] = "", iLen = 0) 
{ 
    if(!iTime)
    {
        formatex(szMessage, iLen, "No time to expire")
        return
    }
    iTime -= get_systime()
    
    new iYear, iMonth, iDays
    new iHour, iMinute, iSecond
    iTime -= iYearSeconds * (iYear = iTime / iYearSeconds)

    {
        formatex(szMessageFmt, iLen, "%s%d year%s", szMessageFmt, iYear, (iYear > 1) ? "s" : "")
    }

    if(iMonth)
    {
        formatex(szMessageFmt, iLen, "%s, %d month%s", szMessageFmt, iMonth, (iMonth > 1) ? "s" : "")
    }

    if(iDays)
    {
        formatex(szMessageFmt, iLen, "%s%s %d day%s", szMessageFmt, iHour ? "," : " and", iDays, (iDays > 1) ? "s" : "")

    {

    }
    copy(szMessage, iLen, szMessageFmt)
} 


To use the command properly:

amx_display_time month/day/year
If you want to know by hour/minute/second, just pass them as hour:minute:second

Example: amx_display_time "10/30/2023"

Time remaining: 1 year and 1 day

Example: amx_display_time "6/30/2027"

Time remaining: 4 years, 8 months, 1 day and 12 hours

Example: amx_display_time "6/30/2027 18: 30:15"

Time remaining: 4 years, 8 months, 1 day, 13 hours, 24 minutes and 52 seconds
