I'm already a registered user, how can I upgrade my current software?

If your software is written for Windows 95 or later, there is no charge. Just download the lastest version from the link appearing at the bottom of its product page. If this is a 30 day trial version, use your Registration disk to remove the trial time restriction.

If your software is for Windows 3.1 or DOS, please e-mail us for details of special offers to upgraders.

I want to print TideComp tables but can only print graphs?

Some times this question is reversed, but you can use TideComp to print either tide tables or tide graphs. Click the mouse in the tide graph region of the screen, then select print from the file menu to print tide graphs.

Click the mouse in the tide table region of the screen and select print from the file menu to print tide table

If in doubt, use print preview to find what's about to be printed before begining the print process.

Why doesn't TideComp print tables with daylight saving time corrections?

The decision to apply a daylight saving correction is under under local government control and though there are standard rules, these are not always followed. For this reason it is difficult to predict exactly how this will be applied particularly during the long validity period of the program. The great majority of published printed tables print predictions for the Zone time of the port in question, which is the convention followed by TideComp.

What are Zone times?

World time zones consist of 24 regions each spanning 15 degrees of longitude. Time zone zero is centred on the Greenwich Meridian and throughout the whole region the Zone Time is UTC (Coordinated Universal Time) which for most purposes is equivalent to GMT (Greenwich Mean Time).

Time Zones to the west are named with whole numbers +1 to +11, and those to the east are numbered -1 to -11. The 15 degree zone centred on the 180 degree meridian is split into two 7.5 degree zones numbered +12 and -12. Throughout each Zone, the time differs from UTC by the zone number of hours.
