Code:

#define LTimer1s                                (1000)
#define LTimer2s                                (2000)
#define LTimer3s                                (3000)
#define LTimer4s                                (4000)
#define LTimer5s                                (5000)
#define LTimer10s`                              (10000)
#define LTimer15s								(15000)
#define LTimer20s                               (20000)
#define LTimer30s                               (30000)
#define LTimer1m								(60000)
#define LTimer2m								(120000)
#define LTimer3m								(180000)
#define LTimer4m								(240000)
#define LTimer5m								(300000)
#define LTimer10m								(600000)
#define LTimer15m								(900000)
#define LTimer20m								(1200000)
#define LTimer30m								(1800000)
#define LTimer1h								(3600000)
#define LTimer2h								(7200000)
#define LTimer3h								(10800000)
#define LTimer4h								(14400000)
#define LTimer5h								(18000000)
#define LTimer10h								(36000000)
#define LTimer12h								(43200000)
#define LTimer24h								(86400000)

Why so hard?

Code:

#define sTOms(%0) (%0*1000) 
// seconds
#define mTOms(%0) (%0*60000) 
// minutes
#define hTOms(%0) (%0*3600000) 
// hours
#define dTOms(%0) (%0*24*3600000) 
// days

Use:

Code:

SetTimer("Function", sTOms(5), false); // 5 seconds

AND THE BEST PART IS:
Google for:
1 minute = ? milliseconds
1 day = ? miliseconds
