how to get auto date and time ( indian time )

Online Attendance ...
when a user log's in

and enters his username and password

automatically the date and time should be captured

this should be shown to me ..(Admin )

However the auto date and time should be Indian Standard time ...i.e +5:30 GMT

the function zoho.currenttime displays the zoho server time and date ?

any possible way i could have indian time displayed ?????
