eto po yung code
nakakapag add naman po nang oras kaso na rereset po yung time like nagiging 59 padin pag nag hulog nang piso ulit

baka meron po kayo reference alam na reference na pag nag add nang time na babawas sa current time di yung nag rereset

Para saan ba itong sineset mo na value sa secUnit?

secUnit = 59;

 

[ribbit]

Para saan ba itong sineset mo na value sa secUnit?

secUnit = 59;

para po sa bawat hulog nang piso

kaso pag nag hulog 1 min tapos po meron 59 sec

slr diko na watch po
