Good morning, it's easy to check if the data entered on a textbox is a date using IsDate functions but how do you check for time, is there a IsTime function?

Also, how do you calculate time in VB. My monitoring system which deal in vehical repair has to monitor the amount time minus 1 hour for lunch break for a mechanic. The difference minues lunch time would then be multiplied by the mechanic's rate to determine the total labor costs.

God bless,
Alvin
